Is there a way to determine an image's width and height from a URL or something else?



What I want to do is load an image and resize (scale proportionally) it to fit the layout.



[updated]

Thanks to your comments I got this working for my needs. Thanks everyone.



my testing code

<?php

//image sizing



$imgurl = "http://www.domain.com/images/image.jpg";



$img = @imagecreatefromjpeg($imgurl);



if ($img) {

$img_height = imagesy($img);

$img_width = imagesx($img);

// imagedestroy($img);

}



echo "My width is " . $img_width;

echo "My height is " . $img_height;




$scale = 200 / $img_width;

$img_xnew ="200";

$img_ynew = round($scale * $img_height);





print("<hr><img src=$imgurl border=1>");

print("<br>$imgurl");

print("<br>scale $scale");

print("<br>$img_xnew x $img_ynew");

print("<hr><img src=$imgurl width=$img_xnew height=$img_ynew border=1>");




?>
