You might also consider a format you can put directly into the 'text' 
property of the image.  You might experiment and see what formats you 
can stuff in directly.  Or you can set it from a file if that is not 
too slow or otherwise a problem.

The function exportPicHandleToFile() here might give you some ideas on 
working with picHandle:
