v1.4.3

In addition to the CORS elimination from the previous beta release, this one adds the ability to use sidecar text files with tags for every image, as requested in #17, fixes the danbooru source field and corrects the https usage for Gelbooru and Booru.org.

CORS begone

This intermediate release introduces the most important fix - complete removal of dependence on CORS-bypassing proxies of any kind. The page code is now injected by wrapping it into a js script file which can be loaded without CORS limitations. This eliminates the instability that plagued the uploader since its creation.

New features include logging only errors to keep the log clean when uploading large amount of pictures as well as producing a batch command file to sort images that caused errors into separate folders by error type. This will help localizing and fixing mistakes when mass-uploading. Scripts should work both on Windows and Unix (although the latter is untested).

Danbooru engine support

Major update.
As title says, the script now supports Danbooru API of both versions (Moebooru and Danbooru), greatly increasing the sites coverage. Current booru engine is automatically detected, but manual override is also possible, choosing among Gelbooru, Moebooru and Danbooru.

Other improvements include:

• Ability to upload whole folders of files (Chrome only)
• Indication of current booru engine and login status
• More informative error messages when uploading (especially on Gelbooru)
• A couple of bugfixes

You're welcome to test the new release on Danbooru-running sites, especially on Firefox.

Better integration

• Login status indication
• Potential support for Gelbooru, Safebooru and other custom boorus
• Use preset tags from your account's settings on the booru
• Fix a problem with tagless images

Public release ready

Well this was easy.
Install the user.js and it'll take care of the rest, adding the link to mass uploader to your booru's menu on top.
