I am trying to insert a picture as a watermark in the header. I have done this before and know how to do it. However, there is a setting in the sheet I am working with that will not allow me to see the watermark. It does not show in any of the views, in PDF, or when printed. I have done this before but with Microsoft 2010 and I cannot remember how I had done this. It is a setting that I have to clear. All I remember is that I need to highlight the sheet I am working with.

Please help this is urgent and I am desperate!!
