Have a DHTML mini Gal inside a post !?

I'm dev' a new version of my site www.sortons.net at www.sortons.net/test-nucleus.html

Look at the left (edito) : you have a pic and 7 thumbs.

How to create a similar mod to put this gallery inside a post ?

Idea would be

[album]url-of-the-album[/album]

It needs an admin control : stock thumbs when created (if they aren't in the root album)

I think it would be very nice when you have several pics to show inside a post.

PS : maybe not in the good forum ... (I don't know if it's feature request, mod, or pun discussion)
