It's a proprietary format, so, essentially, no. But why would you want to anyway? Why not just make a directory of the images you want, run Gimp's Guash on them, and burn the lot (including the hidden .xvpics sub directory) to a CD? You might even want to give people a copy of Gimp for Windows, too!

xpcd will read Kodac Photo CDs.

guash_2.3.0-3_i386.deb works fine with Gimp 1.2.3
