RE: [PHP] Browser Control Help
Rather than trying to prevent theft of your images why not create a little app that steganographs some copyright information... With some thought it's possible to hide textual content within an image At least then you can prove it was yours...

Once the browser has the content, it's out of PHP's hands. It's on the disk of the remote client, and they can do what they like with it. To print an image or web page that's in my disk cache, I don't need to use my web browser - I can just go to the cache in my file manager and print it. Unless you write a dedicated viewing application that must be used to view the content, you're not going to have much luck. If you want a watermark on print, just watermark the image anyway. Steganography might help, but only in the digital world.

RE: [PHP] Browser Control Help
As Dan has correctly pointed out, you can only hope to make stealing your content "less convenient", though only marginally so. If you display a picture on my browser, all I have to do to steal it is hit my "Print Screen" button, then paste it into PhotoShop. There are any number of other ways to get it too. My guess is that Visual Arts students will be pretty good at manipulating images on a computer, and that, unfortunately, you will not be able to thwart a determined content thief.

Re: [PHP] Browser Control Help
Hi Dan, You are sooo right. We know certain kindda people would love to break the code just cuz its there :D I am least worried about programmers. Its stupid rich Art collage kids I am trying to prevent using my stuff. You would be amazed to know I walked in SVA( School of Visual Arts), NYC & saw my painting exactly as is printed in their merit list with a kid's name under. What I want to achieve is, only my homepage will have File, View, Edit menus. I have mapped navigation over images, once they go anywhere it should open a window that has no menus like http://creative.gettyimages.com/ uses for display of images.

You can't (I'm pretty sure of this) remove (or disable) the menus in the browser (security implications there) There are usually ways around these client-side types of protection too... consider that if a person really does want to see your code/steal your pics they will look for ways around the system... Usually these exist with injection of JS into the URL (this is evident in at least 1 commercial system... can't remember what it is though :) ) Also, if a user can get your image path (on hover in Opera, for instance) the image URL can be directly input and stolen from there I decided a while ago to bite the bullet and accept that there are things I can't protect...
