I put copyright on Photobucket image!
You CAN edit your images in Photobucket to add text...
See? :-D It can be sized to your liking and whatever color and font.
I don't think I can do whole batches at a time, but I haven't looked into it too far. But now that my albums are 'private', the pictures don't link back to the rest of the photos, so I can just edit as I want to post one. Later for the FKB, or when I get around to it, I'll just make a new album set to 'public' with all the images edited properly.
