        Great :-)

        Right - there's some more there I guess; if we do:

        bin/g grep 'GetImage *(' | nl

        we get 300+ hits ;-) the majority of these are the other constructor
though; the one that doesn't take a string parameter.

        Soo ... here is a trick ;-) if you have a build (which hopefully you
do) - we need to find the mangled name for this:

   Image        GetImage( const ::rtl::OUString& rImageName ) const;

        compare the output:

objdump -T vcl/unxlngi6.pro/lib/libvclli.so | nl | grep GetImage
objdump -T vcl/unxlngi6.pro/lib/libvclli.so | nl | c++filt | grep GetImage

        and we get:

2412  000f556c g    DF .text  00000081  Base        _ZNK9ImageList8GetImageERKN3rtl8OUStringE

        So by grepping every .o file in the build, we can find how many times
it is used, and in which places:

$ grep _ZNK9ImageList8GetImageERKN3rtl8OUStringE */unxlngi6.pro/slo/*
Binary file framework/unxlngi6.pro/slo/imagemanagerimpl.o matches
Binary file sfx2/unxlngi6.pro/slo/imgmgr.o matches
Binary file sfx2/unxlngi6.pro/slo/module.o matches
Binary file sfx2/unxlngi6.pro/slo/styfitem.o matches
Binary file sfx2/unxlngi6.pro/slo/templdlg.o matches
Binary file vcl/unxlngi6.pro/slo/image.o matches

        And we have five real hits :-) of course, we need to find the relevant
modules that produced those object files - but hopefully it narrows it
down a bit ?

        Ah - I think we'll be ok :-)

        Heh :-)

        Ah - except I already added the res/missing_icon.png for you with the
last commit; and I'm happy to take the hit of just one copy of that with
a sensible name :-)

        Good stuff !

        Thanks,

                Michael.
