Anyone here a whiz at Blogger blogs? I have a question.

I'm adding some pages to my blog. (Here's how in case you want to know.) I would like for one of the pages to be a gallery of all my projects/layouts. I want it to be a collage of pictures side by side and in columns. How in the heck would I do that and still have each image able to open up larger? I guess I could make several collages in Picasa and insert them like pictures but then each one would not be clickable. I wonder if I should just start adding them side by side and see how it turns out? I guess I will try that. 

I guess it would be kind of like a Flicker feed but images of my work all together on one page. Similar to this on Wilna's blog...link.

I need a Blogger smarty pants to help me figure this out.
