You can put them anywhere, but if it is on tcl's auto_path then you
just need a call to "package require tkpng". To check what directories
are part of auto_path, start tclsh and enter "set auto_path".
Follows a sample code to demonstrate how to load the required package:
import Tkinter
root = Tkinter.Tk()
tkpnglib = "/usr/lib/tkpng0.9"
root.tk.eval("""
global auto_path
lappend auto_path {%s}""" % tkpnglib)
root.tk.eval("package require tkpng")
If tkpng were installed in some directory belonging to auto_path, then
you wouldn't need that call to tk.eval.
And.. for tkpng specifically, you won't need tk.call to use it, you
just need to create your images using Tkinter.PhotoImage with a "png"
type.
