33240	get_image_dimensions: ValueError: buffer is not large enough	NKSM	nobody	"When I try to get the dimensions of the image like below: 
{{{
def clean_image(self):
   image = self.cleaned_data.get(""image"")
   if not image:
       raise forms.ValidationError(""No image!"")
   else:
       w, h = get_image_dimensions(image)
       if w != 100:
           raise forms.ValidationError(""The image is %i pixel wide. It's supposed to be 100px"" % w)

           raise forms.ValidationError(""The image is %i pixel high. It's supposed to be 200px"" % h)
   return image

I get :  `ValueError: buffer is not large enough`

**Exception Location**: `/PIL/Image.py in frombuffer, line 2605`

**This works well**:

{{{
from PIL import Image as PillowImage
width, height = PillowImage.open(image).size
}}}
