If your need to is find one software able to process practically all image formats that originate from different sources, you’ve come to the right place. Psion bitmap grey-scale images could be found on Psion Series 3 organizer, which was produced from 1993 till 1998. This organizer was then replaced by more advanced personal digital assistants. There is not much practical use for Psion series 3 bitmap files now, and if you need to convert them into other graphic formats you can do it with ImageConverter Plus.
