Can the Axim see the files on the MMC card?
If it can see the files, have you tried to open them?
If you tried, using what apps and what happens?
The card on the camera will not store the images in a "My Documents" folder, which may make it a little confusing for your software, but for
me I just browse in Explorer (on the Axim) to the files and open them. Piece of cake

I click on the file in explorer and the Resco Viewer opens up and I'm away.
If your Axim cannot read the storage card (see the folders, I think DCIM and HCIM from memory, could be wrong) then the camera may be using a non FAT file format. In which case you're out of luck. I doubt that this is the case though.
