Some step by step instructions for the artist featured art sidebar...
(clicky the images for fullsize)
Take one of the below images
I whited out the top layer instead of making it also clear so you do not need to worry about erasing around the parts of the art that would stick out
Follow these instructions
and Voila
***Other Notes***
I did both right and left mirrored images so you could choose if you wanted to alternate it, or whatever you chose.
AND...Which divider size do you like more? The one under Introduction or Announcements. And did you want it centered at the bottom of each page. Or like it is now, kind of looking like an extension of the sidebar?
