Converting files for Zunes

I just bought a 30 gig Zune yesterday on clearance, and i've started adding files on it, but I came across a problem. I tried converting some pages of comics from .png to .jpg, but when i drag it into my Zune, it won't create the files or directory. The program I used for conversion was Imagicon.

Anyone got any advice?

lol

you have to change the registry values in zune software

my uni library has an e-resource on this, oddly enough
