Woolwell, my phone is HTC Desire, and I transfer the MP3 files by connecting it to my PC as an external drive and dragging & dropping the relevant files. But when I've done the ripping with WMP, I only see MP3 files on my PC, with no graphics file for the cover. Should there be a separate one (as implied by mole1944's reply), or is the info included within the MP3 files themselves?

mole1944, if I get graphics files of the covers off the internet, how does my music player link them to the track that's playing?

The version of HTC Sync that works with my phone has less features than the one described in your link, Woolwell. Even though it was automatically updated not so long ago, it only gives me the option to sync "Windows Address Book (Outlook Express)", and certainly no option to hold down the Ctrl key and select files from anywhere on my PC, or the ability to detect when there's a CD in my PC's drive.

So, if the cover artwork is embedded in the .mp3 files, it must be a matter of one of the settings on my player to view them -- or maybe it's simply that that option's not available with Songbird.
