**Solved!!*** Remove image titles that show up when you hover on images

Hey guys,

I’m trying to follow this guide…

http://kriesi.at/documentation/enfold/remove-image-titles-that-show-up-when-you-hover-on-images/

but when I go to appearance –> editor. It says not to make any edits here. And when I try it in the css stylesheet editor, it doesn’t work.

Please help!
Chris
