[PHP] image protection
Hi gang: What would be the best way to protect images in a directory from being harvested? I know that when an image is shown to the user, while there are some javascript tricks to deter the user, there is no real way to stop the user from capturing the image, for they already have it. But, is there a way to protect a directory such that an application such as SightSucker (nice program btw), can't retrieve it's contents, while your php script can?

Another way that you could do it is setting a session variable on the page that you know your images are going to be viewed from. Then on the script that your images are linked in through (via page.php?image=x) check for that session variable. At least with this second method it forces the robot to accept a session cookie. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] image protection
lurkin' around trying to keep images from others, while still have them shown on yer own page seems a bit futile. watermark 'em. other stuff to do is use flash witch I've never done. (due to PPC restrictions) I've done some of this auto open/close windowing js, witch also includes rightclick disable inside the window; inserting an 1x1 gif ontop, keeping ppl away from direct access of the opened php file with a check of witch location it was accessed from. Insert no-cache in the metadata. This worked on every browser except Opera, witch have some option to disable JS without loosing focus from an window. whereas the gif came in handy This worked on none to eager ppl, while on the other hand; If this image popup was run one time. it could be used one time directly from the address bar due to the browser cache or the session in witch the script were accessed, dunno. Anyone know? Say, stay with WM. On Friday 06 October t2006 19:44, tedd wrote: Hi gang: What would be the best way to protect images in a directory from being harvested?

Tell the client that correctly linked and tagged images INCREASE traffic because the search engines can find them and suck people in, so hiding them is a Bad Idea. :-) But, is there a way to protect a directory such that an application such as SightSucker (nice program btw), can't retrieve it's contents, while your php script can? But it this way: You can erect as many barriers as you like. Some of them will stop some automated scripts. Many of them will stop legitimate use. Most of them will incovenience legitimate users. None of them will stop a determined writer of an automated script.
