Quite some time ago I have written a program for the 8bit to do
right that, extract picture data from program disks. I did it by
copying sector after sector into the screen memory. This should
work on the ST as well if the picture data ist stored in bitmap
format. Wont work of course with compressed pictures. In this case
your program could scan the disk for magic numbers used by the
various picture formats and extract the following data to a seperate
file, then use guck or a similar multi-format browser to see if you
actually caught a picture.
