Holy cow! I was just doing a search about this issue just now! =) I was wondering the same about this, and tried messing with the footer codes in the css file and the header.php file. I even had been working the past few days on making a new image for the footer. Even when I went in to the footer.php to take alot of that extra information out, it just got really small and the image wasn't even there. Just a small tan line where the new information was. Apparently that was the original background color of the whole blog or footer.
I was hoping this job would be easy, but it's turning out to be more of a pain in the arse then anything... =( I hope this can be solved soon, as I had already put enough time into adjusting certain page codings, and even had been working on new images for a look...
Here's a link to the Headspace css file I'm currently working on:
It's been modified though of course. But not that bad, just some color codes and such. I was going to just download another template that wasn't so complicated to edit lol, and just make it the way I want it. But, I had so much time into this one, I really don't want to give up. Please help.. =)
P.S. I just want the image itself in the bottom without margins just as the original poster of this thread.. and really..no margin at the head as well. The idea of this for me is to have a header and footer image locked into position while just the side imagery is there, kinda like it is here at WordPress.org.
