Picture size on grid


I want to include the height and width of the image that is in the file metada on the grid .

I attached a picture of what you want to do (600x600 example).

Thank you

You would have to use an external tool that writes this information to a text file and then import that data into MP3tag.
Mp3tag itself has no function to put picture sizes into tag fields.

You may have a look at this thread on the topic of picture sizes:
