I'm poking around plug-ins/metadata/metadata.c and I want to get gimp_image_parasite_find (image_ID, METADATA_PARASITE) to work.
I'm pretty sure gimp_image_parasite_find expects a parameter of type GimpImage, so I guess what I'm really asking for is the correct API to get the current GimpImage from a plug-in.
No, image_ID is simply an integer. 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.
