Adding a cover image and header image to the Story Map Tour Side Panel layout?

[AlisonDavis-Holland]

I do not see where to add a cover image to Story Map Tour Side Panel layout example as seen in the Palm Springs Map Tour. Can you please tell me where to add that?

Also, in adding a header logo the popup instructions say that the image must be a maximum is 250 x 50px. I assume that this is width and height like the Esri logo. But when I upload an image, it appears correctly in the preview box in the popup, but then the esri logo appears for the header when I click apply.

Thanks in advance for your help,

Alison

It doesn't seem to be working for any of the logos we are trying to use. Here are the URLs we've tried:
