I hit this recently in a similar situation. My solution (actually
it's a workaround) was to use PIL (the Python Image Library) to read
and maniuplate the images. It's easy to draw a PIL image to a window:
image = Image.open('...')
simage = image.resize((...,...))
window.clear()
window.draw_rgb_image(... various parameters...,
gtk.gdk.RGB_DITHER_NONE,
simage.tostring(), -1, 0, 0)
I can do this process all day and not consume memory.
I'd prefer a solution, but this works fine for now.
