What sort of problems?  (What format source image?)

FWIW, I'm able to scale large TIFF images without problem.  (It
does take about 15 seconds on my rather old machine.)
>>> import Image
>>> im = Image.open("/home/jwt/sat1/temp200101.tif")
>>> print im.format, im.size, im.mode
TIFF (8192, 4096) RGB
>>> im.thumbnail((128,64))
>>> im.save("temp200101.jpg", "JPEG")
