Having a Windows laptop and not having a Palm, I haven't used Plucker until recently (or even been able to use Plucker). Now I'm beginning to make e-books for the Nokia 770's Plucker Viewer.

That device has 16-bit color. I opened the CIA_World_Factb-hires.pdb file from Memoware in the Viewer running on the virtual machine in Maemo and the images were solid black boxes.

I didn't think much of that, but a test I ran with a black-and-white photo as a JPEG had the same black boxes. Replacing the image with a GIF worked fine.

I thought, well, the virtual machine doesn't like more colors than 64K, so I ran a test with 16-bit BMP images. Complete blanks in the Viewer.

What formats are most successful for images? Any best practices to follow? If this is old knowledge, where should I go to look?

One further question -- I'd like to include two versions of wide images, one for Palm-width readers and one for the 800-pixel wide 770. How does one put in multiple versions of an image for different devices?

Thanks,

Roger Sperberg
