Unless your original image was a bunch of dots, you have problems.
We have an A60 on a network with several PI's and what you typed above
works fine, though, as expected, the .rgb transfer is slower.

On reading your letter I at first thought you might have prepared your
.rgb images incorrectly and confused them with .rgb files created by
the various iris image utilities such as snapshot. (I know you wouldn't
have done it but many readers out there  are unfamiliar with the a60 
and might have flooded the network with such suggestions. This way I
insult your intelligence rather than theirs (:-))

However, as you rcopied from the a60 in rgb format and tried to send it
right back it should have worked.
