mp3tag embeds jpegs into each song.
i was interested to hear that the i5700 supports ogg files. i've downloaded the latest oggvorbis codec to use with dbpoweramp and converted a FLAC album(which contained album art) to ogg. after conversion the album art has been removed.
the codec info below states that oggvorbis does not support album art.
do you have original uncompressed files? if so you could try one of the other ogg codecs, lancer etc. to see if they support album art.
