Got an iRiverX20. I have tried MediaMonkey and Tag&Rename. Basically, some songs I transfer to the player, that already had cover art embedded into the MP3 worked. Some didn't work, so I re-tagged them and they worked. Now I have had several albums that have taken me ages to get the image to appear. I have had to remove all tag info, use the online search Amazon function, and after several attempts finally the image appears on the player. But I have two albums on it at the moment that refuse to play ball. I have tried everything I can think of. Cleared all ID3v1 and v2 tags. Let search Amazon. I have googled for a pic and put it in myself. I extracted a working .jpg from an MP3 and then used it's size as a template, still no go. The dimensions and size of the pics that are working are all over the place, so that doesn't seem to be the issue. Any ideas, anything, no matter how obvious it seems, I think I am missing something really obvious and can't see it. In Tag&Rename and MediaMonkey, if I click on an MP3 from which the art isn't appearing on my player, the preview box shows a pic is there in the tag. I can't understand what the problem is. Cheers.
