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!
