How do I make a photo the cover of the album?

I need to change the cover Photo assigned by Dropbox.

Dropbox doesnt offer this as a feature I'm afraid. 

 I'm trying to make an album of min pins and I have a picture I want on the cover. How do I go about doing that and where do I go from there?

when sharing music for others to listen I would like to add a image to look at while listening. Where do I go to do this or how to. Thank you in advance

Dropbox has no such feature.
