I have been trying to load some .bmp album art files onto my e250. I first tried to put it inside the album's own folder but failed. I then created a sub-folder under /.rockbox and named it albumart/. Still didn't work. I get the following message: The file 'filename' is not supported on this device. This device can only accept audio, playlist, audio album and folder files."
I have no problem saving album art bmp files onto the SD card and displaying them.
I use Windows XP SP2's explore to transfer files.
Any suggestion, please?
