Thanks to Jim Pendleton of RSI, I have the answer. When creating the
save file I first execute the procedure which contains all the linkimage
calls, then RESOLVE_ROUTINE my main routine and RESOLVE_ALL. Then I do
the save. When I run the application, I first execute the procedure
which contains the linkimage calls and then restore the saved routines.
Apparently this is described in the IDL Runtime Guide, of which I don't
have a copy.

unfortunately I cannot help you with the linkimage or save problem, but
I experienced the same behaviour for CALL_PROCEDURE or CALL_FUNCTION
routines. It notes in the manual that these would not be found by
RESOLVE_ALL, and that is not more than true. One possibility to avoid
*this* little problem is to resolve your GB routine explicitely *before*
you RESOLVE_ALL, using
RESOLVE_ROUTINE,'GB'
It's possible that this would also solve your other problem, *unless*
this has something to do with limitations on SAVE files in conjunction
with linkimage or call_...
