BTW, you can add a custom image instead text using
content: url("imagepath.png")

This topic is resolved ??

As I said, im quite newbie at WP and did not notice my hosting activated a new cache plugin for WP, wich was the matter in not correctly loading the CSS file after editing it.

Anyway, thank you for your help, your time and your effort in developing useful tools for the community.
