In case anyone is interested, I've created a set of banners and badges below.
These are the most popular banner/badge sizes I've seen today.
If you need others created, just post a reply and let me know the dimensions.
All images are hosted at Imageshack on my personal account...so they won't be deleted due to inactivity.
Image locations are listed under the banners. Direct Linking is OK!
