Core structures such as GimpImage do not get passed to plug-ins, so plug-ins can't make use of them. Instead things like images, layers, etc are represented by integer labels. (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. -- Bill
