Poal blocks webp image format, but it allows the post to be made using one, though the post is soon deleted as it was of a webp image.
I fixed that yesterday. You won't see a broken webp post anymore.
What OP is experiencing is another issue. His browser seems to be loading multiple tabs at the same time when restarting or reloading a previous session.
Nice! Thank you very much for fixing that trouble!
I'm sorry that I failed to ask about/report that issue when I had encountered it each time previously. I should have realized that trouble with webp images getting posted had really only started to happen about the time you implemeted poal's fallback for image hosting prior to pic8 going away completely.
I should have recognized it as something not being right and asked you about it. I didn't recognize it as possibly being a bug on poal as I only encountered it with images posted by that one user a few times. It is great to know that it wasn't something he was doing intentionally!
Also great is that I won't need to spend time verifying that a post image isn't a webp being posted prior to trying to open it or view the post. Thank you!
The issue is that some browsers (especially jewgle Chrome based) on some devices/OS is converting images to webp when copy/pasted, but not dropped.
Selection with the "Choose Files" is not possible for webp images (greyed out on computer's file selector), but is on mobile devices (image selector).
I've since added a condition that will return a warning when someone tries to upload a webp image from a mobile device.
