Correct old paths over entire app

[Skyfe]

I just updated an outdated app to the pipeline, and 90% of my css paths are hosed. The old path was: /images/scrollers/upcoming_left.png the new path is /assets/scrollers/upcoming_left.pngSimply put, the first /images needs to become /assets across the entire app.I was thinking of doing a find and replace across the entire stylesheets directory to take /images and change it to /assets . The problem is, I only want to replace paths that start /images, not paths like http://foobar.com/images or /assets/images/foobar.png.My regex skills are lacking but i'm pretty sure there's a dryer solution for this. I'm running rails 3.2, ruby 1.9.3, with sublime text 2...any help is more than appreciated!
