How do I change the main picture on an album?

[Thumbs ↓ if u ♥ me]

Like say hypothetically it's an album with a Cat, a Bird and a Mouse. And the Bird is the main photo when you're in the albums section it's the first one you see, but I want the Cat as the main photo. How do I do that?

Yes, it is possible.
1 - Login to your facebook account
2 - Open the album that you want to change its main picture.
3 - On the top, there is a link named "Edit Photos" click it
4 - In the next page all the pictures will be listed. Each one has a radio button next to them saying "This is the album cover". By default the first one is selected. Change it with the one that you want by clicking its radio button
5 - Finally click the "Save Changes" button below the page and there you go
