I've studied the pdb format after the conversion of the Photo Application and i discovered some standards things like always the record begins with a string DBLK and then a number which i think it means the number of bytes that the jpeg's frame has. And the limit of bytes is 4104 for each record.
I've searched at the PalmOS Developer Forum for this kind of problem but i wasn't able to find anything.
This is a file stream database, handled on the device using the File Stream APIs (FileOpen, FileRead, FileClose, etc.). You can make this on the desktop easily using the tool 'par' from http://www.djw.org/product/palm/par/. It should just be a straight conversion of a desktop .jpg file.
