Hello !
Topic resurrection, and my solution : 2 years after, i have the same problem, my audio system car doesn't read covers oversized 500x500 pixels ... and i have 5000 mp3 to update !
My covers are all in each album folder with name 'cover.jpg', and many many are with large size, over 500x500px. I want to integrate this cover in each mp3 track, resized to 500x500 px.
First step : convert all cover.jpg.
I use program XnConvert. It's same Xnview developper, and you find it here.
https://www.xnview.com/fr/xnconvert/
- i add my general folder with all my albums : all image files shows up.
- i keep only cover.jpg
- add a resize filter : 500x500 with same ratio
- folder output : same, with name cover500.jpg
Launch process, and it' ok : i have in each album folder a new file cover500.jpg.
Second step : integrate cover500.jpg in each mp3 track
I use MP3TAG.
Create a dedicated action
- Menu Action > Action > New, name it "cover500"
- New, select "Import cover from file", name files "cover500.jpg", put in "front cover"
- ok, ok and close.
Add my racine folder with all my albums
- all tracks shows up
- select all
- menu "Action" and select "Cover500"
And that's ok ! All cover500.jpg are integrated in each MP3 track, with the right picture in each subfolder album !
That's all. Long to explain.
But i only need 5mn to proceed all my files ... magical !
