Hi there

Any ideas how I can allow a thumbnail image on the net, that when clicked on to enlarge, slaps a copyright text on top of the image, making it useless for copying? Or allowing the image to enlarge but prevent it from being copied afterwards?

Im creating a website for an artist who naturally enough want their work protected.

Thanks................Jogn in Mosgiel.

The only way I know that will work is to photohshop each image with the copyright over the top. Protecting with javascript etc is easy to get around.

I would of thought putting the copyright watermark on the image before uploading it to the website would work best. You can just put it on the fullsize image and leave the thumbnail as is. There are plenty of ways around downloading/saving an image if a website has disabled the right-click context menu.

You could do it with the GD Library (and using Perl or PHP) to merge in your copyright wording, over the top of the enlarged version.

make a thumbnail with no watermark, when they click on it the full image downloads with the image watermarked through the middle of the picture.

If you stick the copyright top or bottom it can be easily cropped off and the picture reused. If you put the copyright in a plain place it can easily be cloned out as well. So a strong embossed text or watermarked text is semi transparent, or outlined only is best.

Well Ive had a bit of a think about this. If I slice the original pic into 4 equal squares, place them into a table with zero borders/paddng, then make another clear image, equal sized to the quarter of the pic, use the mouse rollover to present a clear transparent atop the portion of the image, so when its right clicked to Save Image, all they get is a clear image with nothing inside?

Thoughts please.

What if they just take a screen capture?

The problem is, as Metla pointed out, that anyone can still screen capture whatevers on the screen. WYSIWYG with screen shots. Only viable option is whacking a big ugly Copyright label over top of the pic.

I'd be thinking of the marketing side of things...

Have a thumbnail, which links to a larger image, say 400 x 600, and which in turn leads to a full screen image which has the copyright label splattered over it.

Reason being for having the mid-sized image freely available should be obvious - to spread the artist's name and work around.
