Have you ever thought about using gs:destroy?
gs is a binding to Tk, which requires to explicitly destroy 
objects. The gs graphics server does automatic garbage 
collection of those non-Erlang objects, but it is done only when 
the process "owning" (i.e. created) the objects terminates.
Cf. section 2.4 of the GS User's Guide.
If you want to destroy objects before the "owning" process 
terminates, use gs:destroy/1.

Id = gs:create(image, ...),
gs:destroy(Id)
