banner, how to position it Options

[MasterChief16]

well, i'm trying to get a banner to be aligned with the blog body, but to not scroll with it. here's an example

if i paste the image under the blog body div box, then it scrolls up with the body and disappears. but if i paste the image above the div box code, then the image is in the middle of the header. and when i try to align it to the right, it goes all the way to the right and doesnt match up with the body. am i suppose to make a frame around it and position it? or put it in a div box?

oh, and another question, on that test site, the links to post comments are really small. i think it's because i embedded a font, but the other links, such as the subscribe links, are normal size. is there a way to change it?

-- oh yeah, i'm gonna make it a mapped image. but i'll do it after i find figure out how to align it.
