Sharepoint Banner Branding
This might just be me being thick, but I have looked about on numerous sites using a google search but I can't for the life of me add a custom banner to the top of my sharepoint page.
For example we are using the SIMS Learning Gateway and have set the theme "SIMS Learning Gateway Student 13-19 Theme" for the staff pages but I want to add our own custom banner, but I just can't get it to work. A lot of the sites mention to edit the themes default.aspx but I can't find this anywhere. The imagie the theme is using is "globaltitlearea.jpg" and I thought this is going to be easy I'll just edit the .jpg but its not that easy!
Please see below the standard SIMS image that I want to change.
Any help will be greatfully received and an idiots guide if their is such thing!
