Looks like it is a bug in the Watermark add on:

I am having an issue also with uploads. The normal uploader works fine, but the flash uploader doesnt work and i get the error in your first post.

Found out my issue was I accidentally uploaded my .psd instead of .png to the watermark add on and it puked all over my forum uploading. Fixed.
