I also changed imagecreate to imagecreatetruecolor because the quality is better. Hope this helps. God Bless Scott Here is the corrected code for anyone who needs it.

function createThumbnail($imageDirectory, $imageName, $thumbDirectory, $thumbWidth)
{
$srcImg = imagecreatefromjpeg(“$imageDirectory/$imageName”);
$origWidth = imagesx($srcImg);
$origHeight = imagesy($srcImg);

$ratio = $origWidth / $thumbWidth;
$thumbHeight = $origHeight / $ratio;

$thumbImg = imagecreatetruecolor($thumbWidth, $thumbHeight);
imagecopyresized($thumbImg, $srcImg, 0, 0, 0, 0, $thumbWidth, $thumbHeight, $origWidth, $origHeight);

imagejpeg($thumbImg, “$thumbDirectory/$imageName”);
}

***notice the “imagecopyresized” now contains …$thumbWidth, $thumbHeight, $origWidth, $origHeight); which is the correct way to resize, not crop the image.

I also changed imagecreate to imagecreatetruecolor because the quality is better.

Hope this helps.

It should be like this: 1. $thumbHeight = $origHeight / $ratio; And it makes a thumb from the top left part of your picture not from the whole pic. You have an error in the code.
It should be like this:

1. $thumbHeight = $origHeight / $ratio;
