Swap Images via MouseOver or Click

I've looked in my sit'es file structure (latest ZC version) and I do not see:

main_template_vars_images and main_template_vars_images_additional

I don't get the instructions at all - sorry to be a pain. Can this be paint-by-numbers explained to me? Thanks.

That contrib will need to be updated- it was written for the 1.2 series and we made some major changes in the 1.3 as you have seen.

Oh cool. Thanks for the clarity. Can the ZC family keep us apprised of this update once it is made available? Thank you.

This mod is what I really need, but I could get by if someone can explain to me how to get the following options to not sit on top of one another. I need to display all options clearly - just so you know what I'm trying to achieve.
