the.com/album cover

means The artwork packaged with a music release — originally a physical sleeve, now mostly a small square image representing the record online.

from From 'album,' Latin for a blank white tablet Romans used for public notices, which came to mean a bound book of blank pages (for photos, autographs, stamps), and by the 1900s a book-like holder for stacking 78rpm records — hence 'album' for a multi-disc or multi-song release. 'Cover' is just the literal protective jacket wrapping the record, which artists and labels eventually turned into a canvas of its own.
