I am using WordPress multisite with BuddyPress and bbPress. I want to specify the allowable blog(s) for an image and then allow it to be displayed as the first entry in the sidebar of every page for all specified blogs.
As an example, if I have a main site and subsites 2-5, I could specify that image 1 can appear on subsites 2 and 4, image 2 can appear on subsites 2 and 3, image 3 can appear on the main site and subsite 5, etc.. When a page in subsite 2 is displayed, I want to be able to select and display image 1 or 2 as the first entry in that page's sidebar.
Does anyone have any suggestions?
