[PHP] Strategy to protect images

Hi all, i have to forbid users of my site to view images directly (i.e. writing the image URL in the address bar) but they'd be able viewing them from the pages of the site. What's the best way of doing it, or something similar? Is there a common strategy using PHP? Thank you for any hint :-)

Re: [PHP] Strategy to protect images

Yes... you can do it. Instade of direct url image, use the url of a php script written(algorithm) below.. ?php /* Write down the code to check authentication of users if( unauthorise user ) then exit from code */ /* Read the image data from file */ header('Content-type: image/jpeg'); /* echo

Re: [PHP] Canvas examples

That's very cool, Richard. Well, thanks, but I wouldn't call it very cool. Now a graphing library that output the results using a canvas, thus negating the need for JPGraph would definitely be nice. Or you could just use JPGraph and get to the pub earlier... :-) -- Richard Heyes

Re: [PHP] Strategy to protect images

This is how I do it: 1) put image files in folder that is not accessable from browser, like outside of http root dir. 2) in the img src tag point src to script like img src=/image.php?imageID=$someID where $someID is the id of image or name of image you want user to see 3) the image.php

Re: [PHP] Strategy to protect images

Must be a windozes thing. :-) I guess so. PrintScr takes a snapshot of the current screen, ie a screenshot and places it on the clipboard. Then you simply paste into something like Paint and save it. -- Richard Heyes Employ me: http://www.phpguru.org/cv
