Or to set a background that is different for each actionblock item and than can set a hover background when mouseover?

Does anybody know?

Problem Solved :)

Want to share in case someone else wishes to do this?

 No Kidding! I came here to ask for this very thing.  I hate when people are keen to ask for solutions, but don't give a rip on sharing them!

 It's probably for the better.  I find the title of this post, and subsequent original question, rather inarticulate and ambiguous.

Start your own topic and clearly state what you want to do, and I'll give you an answer. A screen shot that shows the specific page element(s) that you want to change, would be very helpful.  Well articulated, and illustrated questions, get the best quality answers.

Look up the topic in a search engine; it is done with CSS; I have this for my menu items but I also replaced the Dolphin menu with a custom one so what I did can not help you.  However, it is just like you will find doing a search on image change on mouse hover.
