Follow this short tutorial to find out how to utilize image files as your album art.
Difficulty: Easy Time Required: 1 Minute Maximum per image.
Right-click the album art image and select ‘Copy’ from the context menu.
Next, open Windows Media Player and go to the Albums tab.
I don't know if it's the easiest way, but I use Media Monkey.
It goes to Amazon (you choose which nationality) and auto-tags what it finds. My Classical music is the most problematic, but I find pretty good track listings.
Search for the album you want to add the album art to, and right-click it.
In the context menu, you will see the ‘Paste Album Art’ option. Adding ID3 tags is much easier in Windows 8 & 10 than it is in Windows 7 but it’s still do-able.
Now, click on the Album category to see a list of albums in your library.
To add missing album art, right-click on an album that is missing a cover and select Find Album Info from the pop-up menu.
To check to see which albums in your music library have missing covers, click the Library menu tab at the top of Window Media Player 11's main screen.
In the left pane, if the library section isn't already expanded, then click on the small triangle next to it to view the contents.
You may have seen these images on your portable player (if it's video-capable) and in software media players such as Windows Media Player.
