MP3 IMAGE TAGGING
MP3 JPEG TAGGING
But back to YOUR machine. As each machine differs you can't control the default icon of other people's machines but you can change yours. This is not to write a tutorial on using Windows but on most versions you right click on the file and can change the icon there.
Is it possible to change the "face" (the look)of a MP3 file as it appears on the screen of the monitor before it is opened? I do not mean to download album art from Internet, but to create like a title in Word, for example, and to put it as the new "face" of the MP3 file (instead of the logo of Windows Media Player). Is it possible to use CD-Ripping software to do this? What are the options available? I would appreciate it very much if you give me a hand; helping me out.
