One feature of many media players is the ability to display album art. Creating album info is really easy using MP3-Info. This freeware utility will add another tab called MP3-Info in the Properties section of any MP3 file so that you can chage any property of that file.
After installing MP3Info, right-click any MP3 file and select Properties.
Click the MP3-Info tab and you will see this -
Fill in your necessary informations in other tabs and then click on the Images tab -
The only checkbox you need to be concerned with is Cover (front). You can add in the other images if you like but the front cover is the only one that matters. When you check the box you will be prompted to add in an image file. You can use any image but use a JPG or JPEG as these work well. They can be any size but it’s suggested to have it at least be 320×240 and not more than 800×600.
Once you have the image applied you can open up the MP3 file and your image will show up as album art.
