I'm using Zend_Filter_Input to validate some input, and one of the textboxes allows you to enter a URL in. I need to validate the URL to make sure it is in the proper Website.com format. In fact, it's supposed to point to an image, so I'm hoping I can override the validator (if one already exists) so it checks for a proper image url.

And what is proper image url?
image34534534534534
image.php?gen=23423423423
/image/7234273642734
image.jpg -> rewrite hack.pl

I figured it out, thanks anyway.
