I have 5 pictures, img1.jpg, img2.png, img3.gif, img4.jpg, img5.png. how to determine the picture size, if it is a Horizontal picture( width is more than height)width>=300px and height>=200, then insert into the database? else the pisture is a Vertical picture or width less than 300px and height less than 200px, refuse insert it into the database?

<?php 
$links = array("img1.jpg", "img2.png", "img3.gif", "img4.jpg", "img5.png"); 
$sizearray = array(); 
$count = count($links); 
for($i = 0; $i < $count; $i++) { 
    $size = getimagesize($links[$i]); 
    list($width, $height) = $size; 
    $sizearray[$links[$i]] = array("width" => $width, "height" => $height); 
} 
print_r($sizearray); 
// which will print out: Array ( [img1.jpg] => Array ( [width] => 300 [height] => 400 ) [img2.png] => Array ( [width] => 680 [height] => 330 ) [img3.gif] => Array ( [width] => 50 [height] => 50 )[img4.jpg] => Array ( [width] => 400 [height] => 250 )[img5.png] => Array ( [width] => 400 [height] => 300 )) 
?> 

<?php 
mysql_query("INSERT INTO photo (id,image) VALUES ('', '".$links."')"); 
?> 

This should insert img2.png and img5.png into the database. Thanks.
