I've been using Bliss up until now to find and edit album artwork so that it's dimensions and size are small enough in order for the artwork to appear when I insert the SD card containing it into my car stereo. Does MP3TAG allow me to edit the artwork?
Right click on the artwork in the tag panel to see these options, including resizing.
How small does this need to be? I would hesitate to do this for my library just to show in the car.
dimensions at most 500-by-500 and size 256 kb.
If you usually have larger artwork embedded I would export the covers for potential later use.
