There must be some sort of coding problem on the "Single Image Upload" "Description" input area.
If I just upload the image without filling in the Description, and then going to Managing Images and filling the description, it works.
But I had to go into the Database to delete the existing images, because I could not select them in the manage Images area.
So at this point I'm telling my client to add the description in after uploading the images.
Hope Webassist can find a fix for this bug.
