Hey, Thanks for the heads up but I have a heck of a lot of images and the site has pretty good traffic so I cant afford to do this on the fly, I was looking for something where you just drop all the images into a folder, run the script and pick it up in the output folder all ready for the web. I did a little looking around and found some good photoshop tips, which I converted into an action so now I am gettting some very decient professional quality watermarks in the center of the image which works with all colors....
Thanks anyway. On another note, I dont know if you know this but in swedish "Galen" means crazy :-D You must have been a real bad boy as a kid for your parents to have named you that... hehee (No offense meant.)
