Jquery hover over an image to show caption with transparent colored background on top

When I hover over a thumbnail which is wrapped within an anchor tag I would like the caption to fadein with a background color that covers the entire image regardless of the images size as this will vary.

This is what it looks like before

and this is how I would like the hover effect to look like.

I have found a couple of plugins but none of them seem to support rounded corners on the overlay

Also here is a url.
