No images after capture

[porkyhttp]

I tried to install it on my Raspberry with raspbian buster. I had some throubles with nodejs and npm packages, but i compiled your sofware. So, I startek Ekos with simulators and Ekoslive, but in uoy webpage localhost:3000 is see only string regards mount coordinates etc etc, but I do not see captured images.

I used Chrome 84.0.4147.125 from my desktop pc connected to the Raspberry ip on port 3000. So, as I said, I had problem when build the software because NPM package provided by raspbian is not compatible. I installed nodejs with this procedure
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
sudo apt-get install -y nodejs

and then I was able to run NPM commands with some warnings

Hmm. What version of KStars are you running?

[porkyhttp]

3.4.3

[rickbassham]

I haven't been able to reproduce this locally, using the same versions. Can you try refreshing the page after a failed capture, then doing another capture? Even just the camera preview on the capture tab in Ekos should send a new image.

[rickbassham]

I was finally able to reproduce it, and pretty sure I fixed it. Can you give it a try? Also added several new things to the app.
