Cannot upload images anymore

Since about 1 month ago Roll20 refuses to upload any images anymore. Neither drag and drop nor standard uploads, say for a handout. Always worked before, but now, the best I can do is find little "broken image" files in the recent upload folder. I have tried both Edge (my normal browser) and Chrome. I have disabled all extensions. There doesn't seem to be any Virus program except the standard Windows. I have tried numerous different image formats (not that that was ever an issue before). Jpg, png etc. Saved and re-saved them in different formats too,   I'm at only 4% of my Plus membership storage. The images are small - 150kb some of them. Nothing works. I should be prepping for a game, and here I am hitting the wall instead. Sigh.

Have you tried Firefox? Chrome and Edge are very similar browsers under the hood.  Have you tried logging out and logging back in? Different computer?  Is this always the same game? Or have you tried this in different games?

I was uploading yesterday and 1 image of 8 got messed up somehow.  You should use the Help Center and Send a request for Roll20 staff attention and a ticket to track your issue. It’s mostly community help here. 

Thanks for the comments - yeah, I logged in and out a few times, didn't fix it. Weirdly enough I eventually managed to upload 2-3 images. I thought I had found the issue - that I was trying to upload from a second window, and it seemed to work once I moved the Roll20 Tab back into the main window of the browser? But in the end that wasn't that after all, because it went right back to not working (and not being able to replicate the 2-3 successful uploads).
