mod_rewrite breaking images

[Hypertext]

For instance I have
RewriteRule services services.php

If I go to example.com/services the services.png image in images/top/services.png will (I'm guessing) try and fetch that page as the image, is there any quick work-a-round? I tried using a not ( ! ) pattern, but didn't understand the correct syntax to make it work.

Appreciate help :)

Fixed - needed a carrot before (^), in order to force it to start with services ie

example.com/services
not
example.com/images/services.png

The ^ is used as not in regex.

What are you smoking? The start of a string?
