the first sounds lik3 something i fixed the other day so are you using the latest version?
the standalone artist picture cannot be resized
Yes I'm using the latest MusicBee3_Patched.zip you posted on Jan. 13
This issue occurs with one album where only a few tracks have a secondary artwork. I have other albums like that but they don't have this issue.
For unknown reason the switching works once with one track of this album. When it did, I tried with another track of the same album and instead of displaying that track's second picture, it displayed the second image of the previous track (the one when the switching worked).
