OK...here we goooooooo...

Having only played with HTML and CSS for a couple of weeks now ( and doing pretty good so far even if I do say so myself )...every once-in-awhile I hit a snag...

I'm trying to find out how I can insert images into the sides of my blogs...example...

http://egalitariangraphics.blogspot.com/
Egalitarian Graphics

you'll notice that everything left and right is just wasted space...I'd like to fill that space with pictures and advertising space for rent blocks...

how can I do this? In simple language that a two week old veteren could understand

if you need to look at the page source and tell me where and how to place what I want.

Thanks,

Eg
