I was wondering if there was a way to add cover art to an mp3 file using Java? I'm fine using 3rd party libraries. I have been using JID3(http://jid3.blinkenlights.org/) to add and edit ID3 tags of mp3 files but can't seem to find a way to add cover art to the files. Any ideas?
Java SE doesn't know about the insides of many types of files.
You will have to
either find a third party package that does know how to make the changes you want to make
or you will need to get documentation for the layout of the contents of the file and write code to add to or update the contents of the file. If you find out what the contents of the file are, then we can help you write the code to change the file.
