Add-on Image preview on thread mouse over

#1
I am looking for a Xenoro equivalent of an Vbulletin addon(See attached for example)

This add a preview of a post that just contains images, So you can get a preview of the images in the post without actually having to click and enter the thread

In this example they have 4 images that you can preview if you mouse over the thread title.

Does this addon exist? I think yes, What addon is this?

Thanks.
