To <tozz at kijkt dot tv>:
  The difference is that we have a new streams abstraction 
  layer which allows GetImageSize() to work which whatever
  can be treated as a file.

To <michael dot mauch at gmx dot de>:
  That was what i expected. And it means there is a problem
  with the streams stuff.

Yes, it's the same here - on the local servers it works with both
images, but it doesn't work with the 00645.jpg when I put it on another
remote server.

When I change line 387 of ext/standard/image.c:

                if ((marker = php_stream_getc(stream)) == EOF)
into
                marker = php_stream_getc(stream);
                fprintf(stderr,"%0x ",marker);
                if (marker == EOF)

I see
  e0 ff ed ff ee ff db ff c0
when the image is served from localhost and only
  e0 ff ed 68
or
  e0 ff ed 64 
when fetching from the remote servers. That looks strange, but I'm
afraid I don't understand what's going on here.

I suppose ther is another problem :-)

When i download the image and put it on one of my local servers it
works:

[marcus@zaphod php4-HEAD]$ php -r 'print_r(getimagesize($argv[1]));' --
http://zaphod.boerger.de/php/ext/exif/test/bug21912.jpg
Array
(
    [0] => 389
    [1] => 500
    [2] => 2
    [3] => width="389" height="500"
    [bits] => 8
    [channels] => 3
    [mime] => image/jpeg
)
[marcus@zaphod php4-HEAD]$ php -r 'var_dump(getimagesize($argv[1]));'
-- http://s005.pictura-dp.nl/foto/500px/GAM_017/00645.jpg
bool(false)

Yes, it has indeed something to do with the image. If I take another
image it works fine! But there must be some difference in the PHP
versions since the 2nd pictures only works with PHP 4.1.2, and not with
the latest PHP version.

php -r '$size =
getimagesize("http://s005.pictura-dp.nl/foto/500px/GAM_908/08841.jpg";);
print_r($size); echo "\n";'

works without problems here (PHP 4.3.0), while

php -r '$size =
getimagesize("http://s005.pictura-dp.nl/foto/500px/GAM_017/00645.jpg";);
print_r($size); echo "\n";'

prints nothing. ImageMagick's "identify" sees some strange ipct data in
the second image; probably these make getimagesize() misbehave.
