Template changes needed?

I think I need to revamp the blog template. Some sort of navigational aid is needed to make it easier to find images. I'm thinking that I might add a 3rd column and put mini-thumbnails. More fingernail than thumbnail. I could also add the rules and maybe a brief summary of aims (even though there are no specific aims).

My fear is that adding an extra column could cause problems for people that are using low resolution monitors

Maybe I should add the fingernails as a bar below the header image.

Does anyone have any better ideas?
