Geeklog Forums

I'd like my geeklog site to spit out HTML where all images on the page have the associated image size. This would help browsers render the page before all the data had been d/l. I can go through the templates and fix up the image sizes for statically linked in images, but what do I do about the topic icons?

Any solutions for this or other images on the site, or other ways to make the page render faster?
