What I am looking to do is have a page displaying a dozen or so images, these correspond to various patterns of material.

What I need to do is make it so that when someone clicks one of these pattern images the various color variations for that pattern (several images) are displayed maybe in an area that hovers over the content of the page with a X in the corner to close it and go back to whats beneath.

Does that make sense?

Not sure what it would be called, have tried searching on here and on google etc but not finding anything.

Perhaps this would be done with some jquery / javascript / css etc.

Thanks in advance.
