There is no need to make an .iso image of the "PICTURES" folder. Technically the pictures can be bigger than the 500 x 240 resolution but the avic will resize them. I use roxio and I just burn the CD as a "DATA" cd. It doesn't require anything special. Only issue I had was one pic was "corrupt" but all the others on all the cd's I had made worked. If you want, you can email the pictures you want on the disc and I will burn them for you. (If I get blasted with requests, this might take some time.) You pay the shipping costs is all I ask. (I will also test them before I send them in my D3.) PM for my email.

I copied some pre-made files from here, burned them to my CD through Windows, and they were fine. Haven't tried to make my own, though...not sure what the problem is here.

where are ya'll getting the backgrounds from?

Melissa, I replied to your PM. This clears up the question/answer I gave you. Look at the stickies in the D3 sections for the premade backgrounds.
