The first image:
>>> i=PIL.Image.open(open("/Users/wichert/Desktop/dont.bmp"))
>>> i
<PIL.BmpImagePlugin.BmpImageFile instance at 0x43f490>
>>> i.mode
'RGB'
>>> i.size
(290, 4294967075L)
>>> i.tile
[('raw', (0, 0, 290, 4294967075L), 54, ('BGR', 872, -1))]
and the second image:
>>> i=PIL.Image.open(open("/Users/wichert/Desktop/dont2.bmp"))
>>> i.mode
'RGB'
>>> i.size
(288, 4294967078L)
>>> i.tile
[('raw', (0, 0, 288, 4294967078L), 54, ('BGR', 864, -1))]

Can you print the following attributes for a broken file, before calling load:
pil_data.mode
pil_data.size
pil_data.tile

2009/3/3 Wichert Akkerman<wich...@simplon.biz>:
I have a small routine which tries to verify if an uploaded file is a valid
image. It works like this:
image_data=StringIO(data)
try:
pil_data=PIL.Image.open(image_data)
except IOError: # PIL abuses IOError to report parsing errors
raise Invalid(self.message("bad_image", state),
value, state)
pil_data.load()
(width,height)=pil_data.size
For some images I get an OverflowError on the load() call:
Module PIL.ImageFile:155 in load
self.load_prepare()
Module PIL.ImageFile:223 in load_prepare
self.im = Image.core.new(self.mode, self.size)
OverflowError: long int too large to convert to int
I can not find any information as to what the problem might be. It seems to
only occur for bmp files; jpeg and png appear to work correctly.
This is using PIL 1.1.6 and Python 2.5 on a Linux system.
