i want to change front cover image but it takes previous image which i use, suggest me how to change image on every new song
If you have already got the image in one file stored as albumart then select that file in Mp3tag, open the extended tags dialogue (press Alt-T) and use the disk-button on the right of the image. Enter a filename for the picture file unless you want to keep the suggestion folder.jpg.
The select all the files that should get this album cover, press Alt-T again, press the New-Button next to the empty image frame and select the image file you just saved.
If you refer to a player that keeps the old image although you updated then search the appdata path on your pc for Media Player\LocalMls and delete the LocalMls directory. Media Player stores its thumbnails there und rebuilds them if they get deleted.
Or what was your problem?
