python - PIL returns empty boxes instead of images -

-

i'm trying write program in python 3 using pil , having hard time displaying image...

i using dictionaries temporarily store variables config.ini

usernames={} usericons={} in range(numberofusers):     usernames[i]=config[str(i)]["username"]     usericons[i]=config[str(i)]["usericon"]

later, want display grid images(thumbnails) , usernames user select from

usericonwidgets={}  in range(numberofusers):     usericons[i]=imagetk.photoimage(image.open(config[str(i)]["usericon"]))     usericonwidgets[i]=label(usersselectioncanvas,borderwidth=2,relief=solid,)     usericonwidgets[i].configure(image=usericons[i])     usericonwidgets[i].grid(row=i,column=0)

however, keep getting empty square images should be... no errors appear, white boxes... doing wrong , how fix it?
