I'm doing a web portfolio for my eldest daughter, its to display her artwork.. what is the best way to make it impossible to to steal images?
I guess screen capture is the big problem
The kid's being paranoid, but she's very protective about her work
I was also going to suggest watermarks. You can also write a javascript snippet which makes an alert pop up when anyone right clicks anywhere on the page, can't remember where I saw that (on some Sound FX site).
Screen capture will always be a problem though.
That's the copyright issue on the web for you - you will never be able to prevent stealing when displaying your art on the internet - it's one of the trade-offs you have to accept, I guess. Personally, I don't think redistribution is such a bad thing? Why not digitally sign the pics as well (meta tags and such), so that others will at least see who the author was?
P.S.
About those banners: If you're using FF, try using the extension called
AdBlock Plus. Works like a charm for me!
