What graphics toolkit are you using?
2) without the actual image to replicate it, we cannot try it ourselves.
3) why did you build it from source? Have you tried Octave's PPA [1]?

1) The compiled octave would load and display the image. The graphical front end would crash.
2) I blindly attached the 6mb image to the response to this list. Somebody suggested that was not the best idea. Sorry.
3) I have now tried the PPA route. FYI the PPA for my version of Ubuntu (12.10) contains Octave 3.6.2 only. This will not run the image package which requires 3.8.0 or greater.
The octave3.8.1 that I compiled would run the scripts that I needed to run if I did not use the graphics frontend. As long as I ran from the command line everything worked fine including opening the image. The problem then seems to be with the graphical frontend which in any case wouldn't even open after it crashed a few times.
So to get my work done I loaded 3.6.3 from PPA, uninstalled the compiled version and "borrowed" those few functions from the image package that I needed.
Since 12.10 is not a supported Ubuntu version anymore I thank you for your help and suggestions.
