Haha, I have almost the same problem.

Issue: Tried changing my avatar to something in my phone's library (it was one of the twitter icons from the official site, I think). The error looks different from the one that normally pops up when the picture you're trying to use is too big.
Do not read this:Normal message when image is too big:
It wouldn't go away after I named it and shoved a .png extension on it, either.
Edit because apparently I can't technology: error was "Missing argument 3 for ImageSizeException::__-construct(), called in /home/cr3oh/public_html/libs/image-Field.php on line 212 and defined". Normal error is "Image is too large (236 or whatever, 264 or whatever), limit is (200 x 200)!"

... Ho hum, I may have found another problem while reporting that one. I'll edit this if it doesn't change from the preview.
EDIT: nvm it appears to be more my error than coding error, but just in case,

Issue:
- the images aren't popping up on mobile. Might be due to size, though.
- Spoiler code is popping up strangely. It appears as "Do not read this" rather than the usual box. That might be due to the change in BBCode, though.
