Camera survellaince project with GTK 2

["Prest Alessandro" <prest fisica uniud it>]

Hello,
I'm developing an application that receive photograph from remote camera
via TCP (BMP format, 640x480, approx 1mb per photo) and I have to render
them in a window.

I've made a try with GtkImage but it is very slow (about 1 image per second).

Do you have any suggestion for a quick rendering (10 frames will be enough).
Should I swith to GdkPixBuf? What is the fastest method?

Thanks in advance!
