Plug-ins are programs that GIMP runs that can interact with the GIMP. A
plug-in can call the functions of GIMP and of other plug-ins and so create
effects and manipulate images in certain ways. Most of the Filters under the
Filters menu are implemented using Plug-ins.

For compiling plug-ins you should make use of gimptool. There's a plug-in
template available at:
which you can start from, and you can take a look at the existing plug-ins in
the GIMP distribution or in the Plug-ins registry (http://registry.gimp.org/)
for ideas how to do things.

To load it put it in one of the GIMP's plug-in paths (e.g:

What does the image viewer has to do with a plug-in? You can load images using
the gimp_file_load() PDB function. Code to access its pixel values can be
found under plug-ins/ in the GIMP distribution.
