Yes, this is possible. However it is only applicable when the Normal magazine type is selected.
This option allows you to add a custom image banner that displays along the top of the online magazine. This can be useful for displaying advertisers’ or sponsors’ content.
Multiple image files can be added and they will get displayed in a looped rotation, one after the other. Recommended pixel dimensions for the banner image: 2500 x 60 px. We would also recommend having the content of the banner image aligned to the left.
