Here you can find how to make an new theme starting with the standard one.

if you click on the first link, you see a great tutorial on how to edit the CSS file to make a new there.
now, i have been thinking about that one, and i've come to the conclusion that if you want to use images instead of flat colors, you can just replace some of the code in the CSS like this:
original (sort of original

):
Code:
/* Alternating backgrounds... */
.windowbg
{
color: #000000;
background-color: #E1E1E1;
}
.windowbg2
{
color: #000000;
background-color: #F0F0F0;
}
That part makes the background between 2 posts alternate.
This is my version of it:
First make an image you want to have. (like you can see in the left top corner of this forum)
Code:
/* Alternating backgrounds... */
.windowbg
{
color: #000000;
background-image: url(images/postback1.gif);
background-color: #F0F0F0;
background-repeat: no; /*i'm not 100% sure it it's 'no' or 'none' */
background-position: top;
}
.windowbg2
{
color: #000000;
background-image: url(images/postback2gif);
background-color: #E1E1E1;
background-repeat: no; /*i'm not 100% sure it it's 'no' or 'none' */
background-position: top;
}
that should align the image to the top, and if you make it a gradiant, going from a dark, or a light color to the color you've set in the CSS file, you can really make a cool effect with it

you could also use only the image, but you have to replace the code
Code:
background-repeat: no;
with:
Code:
background-repeat: repeat-xx;
and remove:
Code:
background-position: top;
-
now, you can do this for everything, including the titles, or the background of the whole theme!

I've only added the last part a bit.
