Tried Freshy and LetaPrime. Each OK in their ways.

Both have same banner problemas Reggulus (you can specify a URL but there are no upload or browse buttons, so you have to post the image in a Written post then get the URL as described in post below).

One issue to resolve, if we want to provide a UMass banner for the various customizable themes: Can we preload the banner to be available from the theme options interface?

Also, each theme seems to require different dimensions for the banner image, so we would have to make three distict files (and locate, where?).

Last resort, we could provide a page of banners on some other page in WorPress– that folks can download, but that kinda defeats the ease requirement.
