Watermark Images on the Fly in PHP

I found this cool article at Sitepoint.com about watermarking images on the fly using PHP... Good for stopping pictures from being copied...

Watermark Images on the Fly in PHP

[wr1000]

My stockphoto site at http://www.exchrome.com uses this technology. You will not see a watermark if you go there, because a "transparant" one is applied. What is nice, though, is that by using a PHP watermark, it becomes (as far as I can tell) impossible to download the picture behind the watermark using any method that I can discover. When a user tries to download the photo off the desktop, all they get is the watermark. WR

That's pretty cool

But what if they print screen?

No problem for me, really. At the size and resolution of a print screen, it would be unlikely that the photos would be put to commercial use, which is what I am trying to prevent with the watermark. Since my photos on that site are mainly for designers who are creating banner ads and web sites, printing the photos to a desktop printer does not really cut into my revenue. Good point, though! WR
