because I can see them when I open the file in mp3tag.. mp3, aac, flac.. they all show multiple embedded pictures in mp3tag.. but I can only see one in the artwork tab of musicbee and I can't see any button to change picture and the drop down picture type combobox doesn't do anything
for example with this flac there are 4 files
one is of type "front cover", 3 are of type "other"
what I see is the first picture in the file, which is also the first "other"
in musicbee if I change the dropdown box to "Album Cover" it will not change the photo to what is called "Front Cover" in mp3tag
