I'm want to set a featured image for the archive templates of my theme. To my knowledge, there is not a way to do so in the WordPress Admin (like Pages and Posts).
I was thinking about writing a function that filters through the currently uploaded featured images and matches the template to the file name. Might be a bit complex.
I also know there are theme options. But this seems like a lot to manage.
How would you recommend doing this that facilitates Featured Image administration (Theme -> Header) and ease of maintenance...
if( is_archive() ) {..your image..}
. If you want to change it from the backend, then you indeed need to create a options page for it. (Maybe there are plugins to do this, idk)
