[Image-SIG] Re: PIL && JPG => cannot identify image file PROBLEM

[Viktor Lacina]

tnx a lot.
I'm not sure if it's only occasional problem, because i found 3 cameras until 
now which produces this type of jpegs... and it grows :-) ...we have a lot of 
customers with digital cameras... at final aprox 1 new camera per week ...

maybe it's not bad idea to include this patch to next release.
