my site is running VBulletin, I want to protect web images linking from other web sites.
I use mod_rewrite to block all .gif , .jpg and it works.
However in VBB some images are stored in database and those images are generated on the fly, so how do I protect such kind of images ?
e.g. users self upload avatars are stored in database but store in a file on the disk.
actually that url is an image generated on the fly
