I'd like to have my header banner change every day, chosen (e.g. randomly) from a list/folder of images.
So far I only found plugins that select a random banner per post or per page view, neither is what I want. Do you know of a plugin, or any other way?
Edit: Example. I'm adding a folder to my wordpress installation. This folder contains some header images. Every 24 hours, an random image is chosen from this folder and becomes the header image for 24 hours, until another random image is chosen.
Actually, I don't care how exactly the image is chosen - I'm fine with rotating through all images in the folder as well. The only thing I care about is that the chosen image stays there for 24 hours.
Basically it's the same as if I were picking a new header image manually every day.
