And also to reduce load times! (Although sometimes the resizer makes the image 5 times bigger and look crappier, so there's still some issues with that.)
No no, it seems like an issue with Firefox or with my account viewing it (it works fine in IE).
I can't see it on Firefox at all. Where the picture would be only shows the tags, and clicking Original image doesn't work. Putting it in a new tab tells me "The image “http://danbooru.me/data/35c56a2df5562863a37c3633620dcf22.jpg” cannot be displayed, because it contains errors."
