Thread:Project:Support desk/Write permissions error on image file directories (2)/reply

If you want to allow uploads and scaling, you need to allow the webserver to write to the directory. This can be accomplished by permissions other than 0777, but that is the easiest thing. Note that these permissions are only needed under /images and that execution of php should be disabled under php.

But maybe I'm missing an important bit here: How are you including the images in a page?
