I think there is a call to get image stats without loading it into memory.

The best way to do this and keep the same scale is, a quick example of
this would be;
$maxWidth = 100;
$maxHeight = 100;
$im = imagecreatefromjpeg( 'path/to/file' ); //This of course would
be for a jpeg
$scale = min(100/imagesx( $im ), 100/imagesy($im) );
$newHeight = $scale * imagesy( $im );
$newWidth = $scale * imagesx( $im );
those will give you the new height and width(to scale);

I run php to upload/resize images now.But I have one question:
After people upload images, if we want to resize the image,we must
maintain the original aspect ratio. This prevents the image from
being "stretched" or "squashed".
Now people upload two images.And I need to resize these two images
1) "1.jpg" 40*50
2) "2.jpg" 10*20
My thought:(size is height and width here)
"1.jpg" or "2.jpg" will be "stretched" or "squashed" if we keep them
as same size.
"1.jpg" and "2.jpg" will maintain the original aspect ratio but
different size
Is it right?
Thanks!
