Reading image dimensions with PIL

[Will McGugan]

Hi,

I'm writing an app that downloads images. It rejects images that are 
under a certain size - whithout downloading them completely. I've 
implemented this using PIL, by downloading the first K and trying to 
create a PIL image with it. PIL raises an exception because the file is 
incomplete, but the image object is initialised with the image 
dimensions, which is what I need. It actualy works well enough, but I'm 
concerened about side-effects - since it seems an unconventional way of 
working with PIL. Can anyone see any problems with doing this? Or a 
better method?


Thanks,

Will McGugan
