I'm still looking for the best way to add cover pictures to my flac-ripped CDs. So far I seem to have embedded the binary picture data (when ripping with EAC), I'd prefer to just link to a picture file in a folder. This may not (yet) be possible with mp3tag (didn't find this option at least) but is available by command line https://xiph.org/flac/documentation_tools_flac.html#flac_options_picture.
My idea is that (binary) embedding increases file size (and alters the complete file upon changes) and its a "static" picture - while the reference to a file allows for quick (ex)change of the picture (file) w/o altering the flac file itself. I can also add numerous further pictures from the booklet w/o blowing the size for each flac file (and with padding in metadata, not even touch the music data).
Does this sound somewhat understandable to you (whether you agree on the "advantage" or not)?
Is "linking" somewhere available in Mp3tag?
Unfortunately, by command line at least, in contrast to embedding the binary pictures, it seems to be necessary to list all the picture data (mime type, size, colours) explicitly (as the picture file/link is obviously not checked for that). This is obviously far more work and also would require new tagging e.g. upon replacing the linked picture with a higher qualitiy one.
Do you know an alternative way to achieve what I imagine here?
Hope I'm not too far off-topic/off-mp3tag.
