How do we get rid of cover cards?

[alemons]

My cat stepped on my keyboard and now it says I have put a cover card.  How do I get it to go away so I can work!?

[Michael Pryor]

You can turn off a cover on the image attachment on the back of the card. Click on the card and find the image attachment. Click the “remove cover” link

You can turn covers off for the whole board in "Options" > "Settings".
