Twitch profile picture does not load?

I'm trying to set my profile picture on Twitch for 2 days, but it never stops uploading when I confirm it with "save". I've already tried several images in different image formats, but never actually uploads them.

Has anyone already had the same problem, or an idea why it is?

Maybe it is due to a wrong picture format, after all, there are many. I advise you to google what image format is possible, I hope I could help you something

I tried it and it was actually on the web browser. Firefox had no problems and immediately accepted the picture.
