To get a good response from this group you really need to provide
at least a fragment of your code -- otherwise you'll tend to get
responses such as:

      "Yep, it doesn't work -- that's an error message"      :(

This fragment works:

import Pmw
root = Tk()
Pmw.initialise()

sc = Pmw.ScrolledCanvas(root, borderframe=1, labelpos=N,
                        label_text='ScrolledCanvas', usehullsize=1,
                        hull_width=400,	hull_height=300)
img = PhotoImage(file='img52.gif')
sc.create_image(145,280, image=img, anchor=CENTER)
sc.pack()
sc.resizescrollregion()

root.mainloop()
