I have been looking for a place to do this, I make so many banners for my fanfic and they don't always get commented on, whether they're good or bad, and comments make me a better artist in the future 
Starting off, they will be somewhat Spuffy oriented, because those are the main fics I write, but I'll go on Gimp soon and start making non-ship and other-ship banners, too, now that I have a place to share my art!
I'll start with banners for existing stories, starting with the one that seems favored by the readers; it has the most reads and reviews of my 18 stories on EF.
These are banners for stories I'm planning on writing someday
My Charmed crossovers:
Then there's my AU where Cordy is the Slayer and Buffy a vampire
And finally, the only one I used Photoshop to make, I love it, but I manage just fine with Gimp, too.
(This is also my only non-Spuffy story, technically)
I used Gimp for all but the last one, google to find the images and have dozens (if not hundreds) of brushes that I found on Deviant Art. Most of these are a few years old, my newest is my signature
