this is the way i make my tbns its long winded but works
1) download easy thumbnails a freeware prog.
2)set up a thumbnail folder on your pc so you can find them
3)open easy thumbnails direct it to your thumbnail file with the pics you want resizing. eg i get my album cover pictures from play.com(right click the pic,save as... rename it now to your album eg if your album is called Morcheeba - Hits rename the pic to Morcheeba - Hits, then save)
4)in the options of easy thumbnails you need to set it to a 64x64 pic do not add suffix .tbn i couldnt get this to work. click make thumbnail
5)you will now have an original pic resized to 64x64 but its a jpg....so right click you will see a button called edit click this or open the pic in paint.
6)when the pic is opened in paint do nothing except go to file, save as this will bring up a save options box then all you have to do at the end of the save name is put .tbn
this will then give you a resized pic and a tbn of the same pic that works a treat with xbmp..
7)then what you do with the file is put it in the same folder as the music eg on my pc my albums are kept here
g/music/lps so if in this folder is Morcheeba - Hits(the folder containing the album) g/music/lps/Morchheba - Hits, you put the tbn in g/music/lps not g/music/lps/Morcheeba - Hits
hope this made sense if not reply again and il try to explain it better.
