the problem is not the extern ('img.pd_linux') but rather the tcl-file
'img.tcl', or even more rather the way you try to load it.

assuming that "/home/orm/img.tcl" is an ordinary tcl script file
(text!, not binary), then you shouldn't use the "load" command to load
it; according to the tcl-docs:
> load - Load machine code and initialize new commands.

is this really what you want?
or would you rather have something like the "source" command:
> source - Evaluate a file or resource as a Tcl script
