I noticed there really were none available, so I threw these together:http://fncool.xtreemhost.com/xthbanners.html
I just took the original .png image on the front page, and modified it to fit a couple different, standard size formats, converted them to .gifs to save space and optimized them.
If you'd like to put one on your site, just right click the image... save as... and save it to your computer, then upload it to your site, and paste the link code i provided under each image where you'd like to have it.
feel free to change it as you see fit.
PS, If anyone else has made their own banners, please post them below, if you'd like me to add them to the page, or would like a different size, just let me know.
Yes, I messed with Glenn's images without his permission, but I don't think he'll mind.
