Banner Difficulties

As you can see, I've been getting in touch with my inner scrapbooker. I've been trying to perfect a collage of pop culture pictures, but it is A LOT tougher than you'd think when doing so in Microsoft Word (I tried using MS Paint, but it refuses to cooperate). Things still aren't perfect (note the size distortion), but they are getting better. I've toyed with the notion of just using the four large pictures as the backdrop, but I like the collage look. Still, as far as how things look before blogger.com distorted the banners, I prefer the original one I did; maybe that's a sign that the multiple pictures is a bad idea. I'll get it figured out soon, so enjoy the distortion for now.
