I would like to add a button under my theme manager which shows a thumbnail listing of available skins (that did not ship with the theme when it was installed).
I'd like to feed this listing from a file on a central server that I maintain.
Looking for some advice on how to best implement this within WordPress.
I will periodically add new skins to the available listing and would like for users of my theme to be able to view them and perhaps even see a "new" icon when a new skin is first launched.
I'm also interested in the merits of hosting and serving the file from Amazon s3 vs my own server
