Hi, Let's say i have an image uploader script, i want to prevent the upload directory from executing Php or even html by only showing it as plain text, i've seen this trick in many websites but i don't know how they do it.

Briefly, if i upload evil.php to that directory, and i try to access it i will only see a plain text source , No html or php is executed. ( but i still want the images to appear normally ofcourse)

I know i can do like that by header("content-type:text/plain"); but that's will not be helpful, because what i want, is to set the content-type:text/plain automatically by the server for every thing outputed from the upload directory except images.

Note: i'm running php 5.3.2/Cent OS and the latest cPanel.

Thanks
