Weird image resizing issue with the uploader

so, i just finished uploading and tagging post #3638244, but i had some really bizarre issue along the way.

i tried using the bookmarklet on this link here and the uploader gave me a broken preview and claimed that the picture was 24x24, which is just completely wrong. next thing i tried was going to the direct image link and trying the bookmarklet - same story. i was about to peg this as a bookmarklet issue, but here's the truly bizarre part -- i download the picture to upload manually and i still got the broken 24x24 image. even tried it with all my Firefox add-ons disabled, still no dice. i ended up just mirroring the damn thing to imgur and changed the source link to the Twitter one. don't know if that's frowned upon, but that's apparently what it took to get this really finicky image to work.

coincidentally i had to switch from Firefox to Chrome just to make this very thread as i got the oh-so-helpful "Failed to create forum post" error. safe mode/disabling all add-ons didn't help either. editing posts seems to be fair game, though.

Uploading the image with the bookmarklet worked fine on my test instance. Not sure what's going on here.

"Failed to create forum post" means your post got spam filtered. I'll look into making the spam filter less aggressive. The error message is deliberately opaque because I don't want to directly tell spammers to keep trying until their spam goes through.

i'm not above admitting that it might be my own Firefox installation borking things (i run a few privacy add-ons that are prone to breaking everything), but again i tried it in Firefox's safe mode where add-ons are disabled and got the same result. i'd love to try the upload again on Chrome just to see if it's specifically my computer (running Windows 7, if that matters) but it seems like dupes are against the rules unless they're higher quality.
