So, I made my big image that has the banner and the sidebar on it.
I split the image into the sidebar and the banner and saved the two.
After uploading I post them onto gaia.
When I go to see my submitted post, this happens:

User Image
User Image

I have no idea why it the sidebar is larger, but it is.
So, I am calling out to all of the thread layout makers
that know how to do this! Help?
