This is probably the wrong place to ask as this isn't quite an API matter, so please forgive me and point me in the right direction if it is...
I have an idea where I would like to use php's imagecreate() to dynamically create a background image for a profile on a periodic basis... I'm thinking something along the lines of a 'photo of the week' appearing as a sidebar (on monitors that have a large enough width...) Being that custom background images have to be uploaded from the users local computer, what are the possibilities here? (Could this be done through the API?) Just a rough sketch in my head, thanks...
