The canvas object is using it (i.e. passing to TCL/TK) but not keeping a reference to it. change idata to self.idata and all should be well. > > from Tkinter import * > > class Foo(Frame): [snip] > > idata = > PhotoImage(file="/home/sj/documents/projects/xaed/images/cat_001.gif") > self.idata = PhotoImage ..... > canvas = Canvas(width=300,height=200) Your missing a parent reference in there (self in this case) i.e.: canvas = Canvas(self, width=300,height=200) but when I tested it it didn't seem to matter. I'd guess however that when the layout gets more complex it will make a difference. Rob. -- http://www.victim-prime.dsl.pipex.com/ -- http://mail.python.org/mailman/listinfo/python-list
