WTF? All my photos are gone. How to upload?

What happened to all my photos? I'm trying to upload a new photo and it's not working. What is wrong with this site?

I suspect you are not with in the guidelines.

Here are the guidelines for uploading pictures:

Guidelines:

  * Maximum image filesize is 500k
  * Maximum image dimensions are 740 px by 740 px
  * Accepted formats are JPG, GIF, and PNG
  * Animated images will be turned into static JPG thumbnails

I finally was able to upload a picture but the previous ones I had are gone. Maybe I deleted them and don't remember.
