(Formally, by values of type GIMP_PDB_IMAGE, GIMP_PDB_LAYER, etc, but in
fact those are just integers.)
The value of the image_ID is actually available as one of the params of the
"run" function -- you should be
able to figure out the standard way to access it by glancing at a couple of
existing plug-ins.
