I don't know how many other people know about this, but I thought I'd share it for the people who don't.
Photogiga is an image uploading site similar to Photobucket.
Some features are:
Up to 5MB per upload,
Unlimited Disk Space,
No time limit on storage (Never delete your files),
File types allowed:
jpg jpeg gif tif tiff bmp png swf psd ,
Option to resize picture on upload,
URL uploader.
While it doesn't let you upload more than one picture at the moment, a flash uploader is being developed which I assume will have this feature.
Also, there's only like 3 ads so it loads really fast.
