Thanks a lot Akhilesh
After changing the code in the Theme breadcrumbs file I am now able to see whatever customer header I want to add.
The size is a bit of a problem as the banner needs to be just the right size so that it shows up, but at least I can change the image now.
@windwandel – I found out that to change the breadcrumbs file you need to go to:
– Appearance
– Theme Editor
Then you find the file Akhilesh mentioned by finding it in the folder on the right hand pane.
