[Tkinter-discuss] Embedding Inline GIFs

[Igor Novikov]

Hi,

It seems your GIF file contains features which are not supported by regular
Tcl/Tk
GIF loader. I would recommend you to try using PIL (Python Image Library)
for image uploading.
Also please  note that latest PIL 1.1.7 allows using PNG images with alpha
channel.
I think PNG icons are better then GIF due to full range alpha channel.

Regards,
