Request: Simple image pop-up hover plugin

Hello,

I haven’t found a plugin that does this yet, so I hope you can help.

All I want is a way to popup an enlarged view of an image when you hover over a thumbnail.

I don’t want to create a slideshow or gallery. I don’t want to have to set up a separate page for the function. It can’t happen on a click (because click does something else).

It would probably be best if I could configure the paths of the full size relative to the thumbnail.

Am I shooting for the moon here or is this possible?

Here’s a page that I would use it on:

Thanks for your feedback.

p.s. I’m not too technical, which is why I am hoping for a plugin. Thanks.
