Alternative to exec()?

JMF · August 23rd, 2007, 6:28 AM

Hi! I'm running a script on my site that grabs a picture and shrinks it to a certain size like this:

PHP Code:


			
exec("/usr/bin/convert -resize 186x picotd.jpg picotdsm.jpg");

It hasn't been working lately, triggering an "exec() has been disabled" error.

I can find my way around PHP, but am kind of new to it -- is there another way I can resize the images without using exec()?

Thanks!
Jeff.

Hello,

I just came across your post, sorry if the reply is too late. In case you haven't found a solution or someone else stumbles onto this thread with a similar question, you might want to look at using the (PHP) GD image library. There is a tutorial here that looks like it could be useful for someone with PHP knowledge:

Code:

$size = 150; //Desired width. Height will be scaled Automatically.
$quality = 70; //Desired Quality of Resized Image out of 100.
$pathtoimage = "/path/to/image.jpg"; Path or URL to the picture
$pathtonewimage = "/path/to/newimage.jpg"; Your PATH TO resized picture

$src = ImageCreateFromJPEG($pathtoimage);

if(imagesx($src)>$size)
{
	$xsiz = $size;
}
else
{
	$xsiz = imagesx($src);
}

$ysiz = (((imagesy($src))*($xsiz))/imagesx($src));
						
$thumbnew = imagecreatetruecolor($xsiz, $ysiz);
imagecopyresampled($thumbnew,$src,0,0,0,0,$xsiz,$ysiz,imagesx($src),imagesy($src));
						
imagejpeg($thumbnew, $pathtonewimage, $quality);
