In the previous post, obviously an important thing and then consider that the turnaround in this second delivery. As mentioned earlier ID3V2 structure allows me to embed images in the frame of audio file information. In these short examples with code shows how to save an image (. Jpg files) and then load, ie read the ID3 information and upload the image in a PictureBox control. Always use the TagLib # library.
The first example is a trivial console application in which we can see how to save an image to be the cover image of the disk (frontcover).
Now for the next example we use a simple Winform Application to display the image just upload the mp3 file. The first example is a trivial console application in which we can see how to save an image to be the cover image of the disk (frontcover).

Here we see the result:
advise who have to deal with this type of file , take time to study and understand the code API source TagLib # because it is helpful to understand how they work to make things very interesting in applications that handle ID3 Tags.
I hope this information will serve and Happy Programming!
