MP3 files can store extra data (called metadata) in the form of ID3 tags. This information is usually added to the beginning or the end of the MP3 file. The image file should be either a PNG file or a JPEG file if you want to view the images in iTunes or an MP3 player. It is best to choose artwork that is no larger than 300-by-300 pixels if you want the image to be displayed correctly in the player. Click on the file or files you want to edit. Right click in the image window on the left side of the screen under the “Directory” text box. There will be existing album art or the picture of a record in this window. Choose the “Add cover” option from the menu that appears. Browse to the location of the image file you want to use and click “Open.” Click on “Save tag” under the “File” menu to save the new artwork to the file. If you want to add the same picture to more than one MP3 file, hold the “Ctrl” key down as you select the files. Once all of your files are selected, you can right-click on any of the files and click “Get Info.” Writer Bio
