Help With Applying Classes To Image Links

[robototitico]

I downloaded the "IMG Mouseover" plugin for my wordpress.

It should be quite straightforward to apply it to an image, however I am having difficulty.

Here are the instructions:

WordPress › IMG Mouseover « WordPress Plugins

MY GOAL: What I'm trying to do is to have a small image A, that when moused over results in larger image B popping up.

This allows you to create a simple image mouseover feature by adding properties to an image:
It understands the following attributes which can be added to the HTML:

• img.class="mouseover" (activates IMG mouseover for this image)
• img.oversrc (If specified, this rewrites the image on mouse rollover)
• img.clicksrc (If specified, this rewrites the image on mouse click)
• img.noresize (If set, this will make the image have the natural dimensions instead of the dimensions of the original image).
• a.class="mouseover" (activates A tag as a controller for another image, when clicked a class "selected" is tacked on)
• a.for (Should be specified to point to target image. Image must be class mouseover)
• a.for_link (If specified the ID of a link is replaced with this one)
• a.src (If specified, the click will replace the image with this)
• a.oversrc (If specified, the click will replace the image mouse rollover with this)
• a.clicksrc (If specified, the click will replace the image mouse click with this)

THANKS!
