Suddenly, the loader does not display the thumbnail image.

[Neytiri7]

One day suddenly, checkpoint, Laura loader doesn't show the thumbnail image.
It's not coming out all of a sudden.

It's embarrassing because it's coming out well and not coming out.

This custom node cannot be deleted and reinstalled,
I reinstalled the CompyUI at all, but it comes out in the beginning and doesn't come out again.

I would appreciate it if you could let me know if there is a way to reset the item or change the settings.

"Lora Loader 🐍" node no longer shows image previews on mouse hover too.
Apparently, the ComfyUI_frontend has been updated (now the mouse scrolling speed in drop-down lists is fast and a scrollbar has been added) and because of this it doesn't work as it should.

I reinstalled it, checkpoint node, Lora node, both come out fine.
Since when did it become right not to come out of Lora node???

As you can see, I reinstalled it, so you can see that it comes out normally.
However, it doesn't come out all of a sudden, and the image will be displayed again only after reinstalling the ComplyUI itself.

[123LiVo321]

Seriously?! Reinstall the whole ComfyUI itself? Come on... I also did reinstall the ComfyUI-Custom-Scripts, but it didn't help. I can't find anyvhere that 'Badge' option, if that could have something to do with preview images on mouse over...., eh.... ??

I just installed the comfyui new, and Python, custom node got the old one.

I think the problem is intermittent, and once it happens, the thumbnail doesn't show up continuously, so I think the only answer is to reinstall the comfyUI.

So, I'm trying to avoid touching UI-related settings as much as possible.

[123LiVo321]

I cannot accept that as a solution, I will not re-install the whole thing.....

[Neytiri7]

After updating the ComplyUI manager, it is confirmed that the thumbnail does not come out.

I am also curious if there is a way to preview lora,checkpoint,etc

[123LiVo321]

I am also curious if there is a way to preview lora,checkpoint,etc

What do you mean??

When you use for example 'Pythongosss Lora Loader' (it DOES the subfolders!) - in the rolette of available loras you can see the preview image on mouse over (if you have some image of the same name as lora in the same folder) - or at least you was able to see the preview in the past - thats the problem - now the on mouse over previews are gone...

The subfolders menu is crucial, when you have tens of dozens of loras managed in subfolders structure, thanks god for Pythongosss, and the mouse over preview is/was another add to quality of work

So, are you saying that it's policy that the preview image doesn't come out from the LORA loader?

When you reinstall the ComplyUI, previews are coming from both the checkpoint and the lora loader.

Currently, once you click on the update through the Compuyi manager and restart it,
The problem is that it doesn't come out from then on.

The part about the submenu seems to be a different issue.

It seems like you don't understand me correctly. I have a little bit of issue to clearly translate your english into my english, so to speak :D submenu/subfolders isn't issue at all. I just mentioned it to praise the Pythongosss's work. The only issue I have is with that on mouse over preview -or as you called it- thumbnail images. Exactly as you posted and documented above in your screenshots. Thats all ;-)

Just want to say - my current version:
ComfyUI: v0.3.10-35-g916d1e1
(2025-01-06)
Manager: V3.3.12

[murphylanga]

I have different versions of Comfy running, this one is relatively new and the preview images still work.

In the most recent version of Comfy, the preview of the images no longer works. It doesn't matter whether it's a Lora loader or a Checkpoint loader, the error probably has the same cause. I upload the information about the versions as images.
the custom nodes ComfyUI custom scripts should be the same: 2025-01-02

Everything still works here:

No more images are displayed here:

[murphylanga]

I have a workaround for you:
Quit Comfyui.
Under ...\ComfyUI\D:\Special\ComfyUI_windows_portable\update
Run the file update_comfyui_stable.bat.
I can't say what it looks like for older versions.
Here is a picture of which version my ComfyUI has now.

[123LiVo321]

i did the update, my current version still doesn't show the thumbnail...

edit: i have the normal version, did a git pull for comfy and for manager...

so you say @murphylanga to downgrade the frontend to 1.5.19? Idon't know how can I do that... :( (yet ;-) )

I am the same.
In the meantime, I've updated it manually using git pull...
Now, I have to update it only through the Manager, so I think I should use it without thumbnails.

[murphylanga]

Run update_comfyui_stabel.bat
Quit Comfyui.
Under ...\ComfyUI\D:\Special\ComfyUI_windows_portable\update
Run the file update_comfyui_stable.bat.

This is done in no time, you change your Comfy to the last version that was marked as stable

[123LiVo321]

@murphylanga : I do not have the portable version, so doing update by 'git pull' , also git pulled the manager... you can see I have newest freshest version up to date on the picture I postet above, but still do not see the thumbnails...

[murphylanga]

@123LiVo321
Your problem is that you have the latest version!!!!!!
Your version is not released as stable!

[thrabi]

Download ComfyUI_frontend v1.5.19 (https://github.com/Comfy-Org/ComfyUI_frontend/releases/tag/v1.5.19) and replace the files in the Comfyui>>web folder. It fixed many problems, including the Model Preview, for me.

[123LiVo321]

@thrabi thats exactly what I mentioned, downgrade the frontend! thank you very much!

IT WORX (just replace + refresh the browser, not need to restart)

Thank you for the good information.
I tested each version, and the thumbnail comes out in a specific version
Especially, the latest version doesn't come out.

If it doesn't come out, I think we need to downgrade the web folder to a specific version.

Considering this, it would be nice if you could work on CompyUI, manager, and custom node side.

I have no thumbnails on checkpoints or loras??

It takes me here: What do I download? The assets files?

[123LiVo321]

just download the zip > inside will be the folder called 'web' >> replace this 'new web' instead of that 'old web' folder and refresh the UI in the browser (F5)

EDIT: ok, so there is not folder 'web' in the zip file, the zip file contains the contents of the web folder. Sorry for that, but it looks like the minor issue for me...

[thrabi]

just download the zip > inside will be the folder called 'web' >> replace this 'new web' instead of that 'old web' folder and refresh the UI in the browser (F5)

Inside the zip there is no WEB folder?

Extract the contents of that zip file and replace the files in Comfyui>>Web folder.

Does it have to be a specific version? Or the newest? I did download the newest and copied it, but still don't have thumbnails. Not my day... :-( I did do a full restart and refresh.

Care to read the above comments before replying?

I don't think I can see the thumbnail from a specific version. However, I can't figure out which version that is. There are so many versions...

So, you can download and overwrite a specific version, or you can also overwrite the web folder that is currently in the ComplyUI installation file, and the image will display normally.

And, the web folder seems to be part of the UI and node design of the ComplyUI, so the node looks different depending on the version.

I've also selected a few and covered them since the version I told you about above...
It has a unique node shape.

[123LiVo321]

I feel sorry for you, I laugh at your stupidity! Growing up is something you need to do! Get off my case, or will report you. This is a place for help, not your petty remarks!

lets recapitulate : so you came here in the moment when the issue was already solved. You just read the title and immediately fire up your keyboard like good old ten year old with "I have no thumbnails on checkpoints or loras??" ... <<< is that a question or you just yell at us? If you just read 3-4 latest posts, you would find your solution. But no, you are a good 10 year old so you yell help, heeeelp, HEEEELP!!!! I can't read, I don't understand even the basics....HEEEEELP!!!! Tell me more about stupidity, seems like you studied that topic alot...

Don't forget to report me ;-)

[christian-byrne]

You can specify what version of the frontend you want to use in the startup args. You don't need manage download and replacing files yourself.

For example, to use the version of the frontend mentioned in this thread (1.5.19), you can start ComfyUI with the command:

python main.py --front-end-version Comfy-Org/[email protected]

[Neytiri7]

@pythongosssss I checked the top version one by one...
It has been confirmed that thumbnails have not been released since version 1.6.14.

There's no improvement in the latest version of 1.7.11

[DeepSeaCatz]

@Neytiri7 For portable, I found that the web folder of version 0.3.10 is last version the thumbnails shows up. 0.3.11 and 0.3.12 stopped showing it up.
https://github.com/comfyanonymous/ComfyUI/releases/tag/v0.3.10

So I guess for people who use Portable, download that zip of v0.3.10 and replace the web folder under ComfyUI folder.

Only visual issue I see is that the light hover of the folder isn't correct, it's stick at the top (hovering XL right now):

Lora Loader Stacked Advanced from https://github.com/idrirap/ComfyUI-Lora-Auto-Trigger-Words use the same logic of Customs Scripts and it works with 0.3.10 now:

Edit: I just realised the portable version was in the image

The frontend version is 1.5.19.
Up to the 1.6.14 version, it will output normally.
It does not output normally from later versions.

Regardless of the ComplyUI version, there is an error in the output depending on the frontend version.
Currently, the problem has already been confirmed by the person in charge of CompyUI, and there is a possibility that it will be corrected later.

I flagged it to the ComfyTeam, which they've pointed me to a previous issue that explain exactly our problem:

Hey guys, so....is the only way to address the issue to downgrade the version? I'm having the same issue with the preview image being dismissed.

Hi, Provide a temporary solution

use editor like notepad++ open .\ComfyUI\web\assets\index-Cf-n7v0V.css (or index-something.css about 94kB)

Find (near line 27)

max-height: -webkit-fill-available;
overflow-y: auto;
}

/* Enable scrolling overflow in Firefox */
@supports not (max-height: -webkit-fill-available) {
.litegraph.litecontextmenu {
max-height: 80vh;
overflow-y: scroll;
}
}

Replace

}

Find (near line 3553)

background-color: var(--comfy-menu-hover-bg, var(--border-color)) !important;
color: var(--fg-color);

Replace

background-color: var(--comfy-menu-bg) !important;
filter: brightness(155%);
will-change: transform;
color: var(--input-text);

Save and reload Comfyui in your Browser, the loader should be display the thumbnail image now.

I don't know what will broken. So... Use at your own risk! and remember backup the file.

can you push it to developer to look at it? it take pretty long time to solve ....

[Flymok]

It's a little bit difficult.
Because them just restore Comfy-Org/ComfyUI_frontend v1.6.8 v.s v1.6.9 and v1.6.14 v.s v1.6.15's change.

I don't know how to actually fix the problem without breaking new features.
