Ok, so while puttering about one day I found this neat script/app called Lightbox. I mentioned it briefy awhile back
Example:
http://www.huddletogether.com/projects/lightbox2/
for support go to:
http://www.huddletogether.com/
or you can email the coder, their email should be on both sites I believe.
Originally I had a tutorial but, it just seemed a bit convulted, and the basic instructions are on the actual lightbox2 site. The only thing I suggest is to insert the code not only in your main index template but also in your category archive/single-entry archive/and date archive.
