php getimagesize() function returning the 1, 1 (Width, Height)

Question

When I run getimagesize() with individual image files with this code

$list = getimagesize("http://img.bleacherreport.net/img/images/photos/002/386/662/hi-res-159212879_crop_north.jpg?w=650&h=440&q=75");
echo '<pre>';
print_r($list);

it returns

Array
(
    [0] => 650
    [1] => 440
    [2] => 2
    [3] => width="650" height="440"
    [bits] => 8
    [channels] => 3
    [mime] => image/jpeg
)

But when I run getimagesize() in a loop

foreach ( (array) $image_list as $imagepath )
{
$list = getimagesize($imagepath);
echo '<br/>'.$list[0].'-'.$list[1];
}

it returns 1 - 1 . This is my problem. it is returning this array if i print the $list array

Array
(
    [0] => 1
    [1] => 1
    [2] => 1
    [3] => width="1" height="1"
    [bits] => 1
    [channels] => 3
    [mime] => image/gif
)

Array List for foreach loop

Answer 1

The reason why some of the images return 1 - 1 is because the images are simply 1x1 . I just ran the code myself and downloaded the some of the images which returned 1 - 1 and they were 1px by 1px.

eg this one is 1x1: http://pixel.quantserve.com/pixel/p-3a-0o8sJKz6Ek.gif
