PHP image resize script

[petenaylor]

Hi all

 

The below piece of code resizes some size images and not others. For example, an image in landscape size of 800 pixels by 600 pixels works OK, but if I try and upload a portrait image the same dimensions it just gets stuck?

 

Any ideas?

 

if(!empty($_FILES['image1']['name'])) {
$imagelarge = $_FILES['image1']['tmp_name'];
$imagelargemain = $_FILES['image1']['name'];
$pathInfo = pathinfo($imagelargemain); 
$rand = rand(1, 100000000000000); 
$name = $rand . '.' . $pathInfo['extension']; 
$src = imagecreatefromjpeg($imagelarge);
list($width,$height)=getimagesize($imagelarge);
if ($width > $height) {
$newwidth=600;
$newheight=($height/$width)*$newwidth;
}
elseif ($height > $width) {
$newheight=400;
$newwidth=($width/$height)*$newheight;
}
$center_x = (600/2)-($newwidth/2);
$center_y = (400/2)-($newheight/2);
$tmp=imagecreatetruecolor(600,400);
$white = imagecolorallocate($tmp, 255, 255, 255);
imagefill($tmp, 0, 0, $white);
imagecopyresampled($tmp,$src,$center_x,$center_y,0,0,$newwidth,$newheight,$width,$height);
$filename = WEB_UPLOAD."images/adverts/". $name;
imagejpeg($tmp,$filename,100);
imagedestroy($src);
imagedestroy($tmp);
$image_sql = mysql_query("UPDATE `adverts` SET image1 ='".$name."' WHERE id='".$advert_id."'") or die ("Error updating database");	
}

 

Thanks for your help.

"Gets stuck"... where? What happens? What doesn't happen?

 

How large (in bytes) are the two files?

Hi there

 

The script just freezes so the browser just gets stuck on the page.

 

I have tried it with a few different file sizes; 60KB, 700KB and 1.2MB but it does the same with each?

 

Thanks

Does "freeze" mean the browser keeps trying to load something? Or it stops and you don't see anything on the page?

If you do a View Source do you see anything? Have you made sure that display_errors=on in your php.ini? (If not, set it, restart the web server, and look for error messages on that page.)
