thumbnails Options

[Smarmosaur]

ok, i'm pretty sure this has been asked somewhere before, but here goes.

i want to be able to click a thumbnail on my website and open the graphic in a new window, that automatically resizes for the image. it would also be nice to use that new window if another thumbnail is clicked, so that the new image replaces the old one, and that auto resizes.

i have no clue what type of coding or whatever is used to do this. i want something simple, because i'm going to have dozens of these floating around my site. i'm just simply asking for somebody to point me in the right direction.
any help appreciated! :]

double postttt!

but, i really could use some help...
the lightbox was working absolutely fine until mentioned in one of my previous posts. now i can't figure out for the life of me what's going on. i didn't change a thing and it just kind of stopped. remember i'm using this through a Nucleus blog from my website.
oh, also, should i just put the CSS for the lightbox in with my page CSS?
here's a link to the directory thingy, where all the lightbox files are uploaded: http://rockitstudios.890m.com/nublog/skins/portfolio/images/

nevermindddd, major blonde moment, i figured it out in a snap.
'cept the CSS, i haven't done anything with it yet so should i just go ahead and stick it in my page CSS?
also, this is probably really obvious, but how can i go about putting equal spacing between each thumbnail without using a table?
