I found the solution myself - when I tagged the mp3 files I failed to notice that the tags were saved as utf-8 coding instead of utf-16. When I changed to utf-16, the embedded images appeared as they were supposed to do.
I think there is a moral here. I was getting worried by all the negative comments I was seeing about the 2.02.32 firmware update - was that the cause of the problem I was seeing? It wasn’t, and this illustrates the point that when something goes wrong, or seems to go wrong, it is not always due the obvious reason that first springs to mind.
