<?php
$logo="demo/whatever.jpg";
$logosize=getimagesize($logo);
print $logosize[2];
?>
$logosize[2];
If it prints a 2 then its a .jpg file - cant remember what 0 , 1 , 3 ,
etc stand for .
[0] is the width
[1] is the height
[2] is the image type
[3] is the width and height
<img src="<?php print $logo; ?>" width="<?php print $logosize[0]; ?>"
height="<?php print $logosize[1]; ?>" border="0" alt="">
As your grabbing the image info anyway - its usually a good idea to use
the width and height stuff as it saves the webpage from jumping all over
the place .
