Does the trial version have full capability?
I'm placing a .jpg image file within two or more .mp3 sound files, but I don't seem to be able to save the newly altered .mp3 files. If this can be done with the trial version, please provide a tip on how to do that. Thanks in advance for the tip.

It's hard to tell what's not working for you given the limited details. Here is an explanation of the feature:
Mp3tag saves the changes automatically whenever a change was made and you change the selection state of the files in the File List. If you don't change the selection, the Save button is enabled and you can save manually.

There's no "Save as" option anywhere that I can see.
Changes in the app did not "automatically" change the original files on the computer.

Can you please describe the steps you take to perform these changes? I might be able to then better understand what's happening.
Also, how do you observe that the original files are not changed? Is this in a different program or is the change also not visible in Mp3tag?
