Viewer for large images

[Toralf <toralf procaptura com>]

Does anyone know of a freeware image viewer, preferrably with a 
GNOME/Gtk interface, that will handle large images (or should I say 
*real* image data, as opposed to desktop backgrounds, icons or other 
decorative stuff)? - The ones I've tried all make the assumption that 
the all data from the file will fit into memory, which simply won't do 
for the images I'm working on.
