I have not seen this on here before, so hopefully someone will find this useful.
I was googling for some secure picture information and came across this website. http://picmarkr.com/
. It seems to be straightforward and can watermark up to 5 pictures at a time. Much more convenient. You can add text watermark, image watermark or tiled watermark. This may just be my new way of doing things.
Hopefully this will help some of you.
