User Problem

When users upload images for a card cover, it's still considered as an attachment and shows up on a card front, while default Trello card cover options don't show up as separate attachments. 

Suggested Solutions

Don't show the attachment (clip) icon on a card front, if an image is uploaded from the "Cover" menu on a card. 

Current Workarounds

Disable card covers for the entire board (Card covers can be disabled on a board by a board admin. To turn them off, open the board's Additional Settings in the board's Menu and uncheck "Card Cover Images Enabled"). This means it can be disabled.
