Seems like it will work great for exclusive content. Not so good with purchased content.

wow, that's pretty damn neat.
Definitely gonna install that.

Might want to rethink your method of data injection.

Open, resize 1 pixel, save, ...good-bye water mark.
Used Photoshop 7.

sure. if there's interest, i can add a more advanced mark. the downside, of course, is a decent hit to the server's cpu.

Shifting pixel colour values at set points somewhere defined
by webmaster would be harder to circumvent.

Appending is not such a good idea as 80% of us use some kind
of copy bug on the edge of an image. When content theives
do their thing, they usually crop these off.

I wouldn't be too concerned about the CPU hit, enough sites
use the GD library very effectively in high traffic enviornments.
Sextracker comes immediately to mind.

no? a pixel-mod (like you suggest) could increase the cpu requirements 5-10-fold for EVERY image downloaded.

better perhaps would be to insert the data into some jpeg header which is preserved across saves. the comment field. or a color-correction field.

if anyone would like to contract me to do this work for them - don't hesitate to write.

as i mentioned on the webmast board - i've put-together a version of porntracker which uses watermarking to encode the tracking data into the image.

tracked images can be resized and cropped by 50% without losing tracking data.

contact me directly for a demo. [email protected]
