I was hoping someone may be able to guide me in the right direction. I want the header in a custom master page to have a background image that can be changed by an 'owner' in a user friendly manner.
The image(s) will be stored in a picture library on the root site and the master page is applied to all sites and sub-sites.
I had an idea whilst writing this post of using the logo URL option in the settings of the site.
Does anyone have any suggestions as to how I can achieve this?
Thanks in advance,
