Is there a way to make a picture demonstrate a custom text when you place your cursor over it while it's in a table? For example, I'm adding little green faces to the top table on this page, and I wanted to specify which episode they came from without ruining the format of how the green faces are placed next to each other... It's kind of an odd question, and I hope I'm explaining it right, but any help would be appreciated on how to do something like this since I'm still new to the MediaWiki coding specs.

P.S. - If you know about any (certificate) program, online step-by-step walkthrough, or book that could help me specifically with MediaWiki coding (excluding the content on here), please let me know. I'm very intent on learning more about it so that I can help the sites I run become what I envision them to be.
