Re: [PHP] dynamic water marks?

2002-06-18 Thread Justin French

The only ways would be:

1. dynamically add the water mark to the actual image (change the pixels) so
that the source file has a watermark.

2. add a css layer on top of the image that contains a watermark


Which brings me to the question, why don't you just add a watermark to each
image?  If a css layer or anything esle that DOESN'T change the source file
was employed, it would only act as a very mild deterent.

Why not just set-up an action script (macro) in Photoshop to batch process
all the images with a watermark... end of story.

 a user up loads a simple image to the site say in jpg format
 when the image is displayed on any page a watermark is disply over part of

Or, if the watermarks *must* be dynamically generated and visible, use
something like ImageMagik to lay something transparent over the image on the
fly. Wouldn't be exactly speedy, but would do the job. (I've seen this done
on a few sites before -- visible graphic watermark is customized for the
logged-in user.)

You may be able to pull this off with the GD 2.01 tools also ... I haven't
messed around too much with the alpha transparency capabilities the 2.01
library allows. ( http://www.php.net/imagealphablending )
