I have been programming for close to eight years now, have been using
computers for as long as I can remember; for the most part I've been
able to figure out anything on the computer.

But I have only been into PHP for a little less than a year, and have
just (in the past month) realized I need an automated image editing
program for my work.
I am currently developing a photo-based site, this is still in alpha
form, so ignore it's UI, it is no where close to what it is going to
look like.

I tried to do as much research as possible about GD2, but could not succeed.
I'm using Apache 1.3.29 and PHP 4.3.5 (non-installation --if that
makes a difference) on Windows XP; and GD library (version 2.0.17 -- I
think...whatever comes with PHP 4.3.5).

I have the GD2 extension in the PHP.ini file, and it seems to be
accessing the .dll fine, but when I try to use any of the GD commands
I get weird results. It would be best to show you. I have, on a
previous version of my site, a screen shot of what I get: 
http://24.127.21.245/osp/photo2.php?img=error_ah28944473.jpg there is
also another screen shot on the site of something else I got. The
source I used to get these results can be found at
http://24.127.21.245/osp/resizing.zip. If you look at the file in
there, you will see that I have many versions of code that I'm trying
to get any type of results from. And the PHP settings I have currently
can be found at http://24.127.21.245/osp/phpsettings.zip.

If for any reason you need to log in to test something on the site,
username: google --password: questions  (I don't care if "the world"
can see this; when I get my answers this /osp/ site will go away).

So my main question (to summerize), I want to know why I am getting
these weird results and no the images I want. And maybe you can write
a short script to give me an example of how to resize an image (one
that works independantly...just enter the images dir/name).

Thanks,
Brandon

// this script resizes an image '/tmp/icon.jpg'.
		// result image: max height=100, max width=200;
		
		$f_src = '/tmp/icon.jpg'; // modify it
		$f_dest = '/tmp/resized.png';// modify it
		$newW=200; // modify it
		$newH=100; // modify it
		 
		$size = getimagesize($f_src);
		if($size[2]==1)	$srcImage = imagecreatefromgif($f_src);
		if($size[2]==2)	$srcImage = imagecreatefromjpeg($f_src);
		if($size[2]==3)	$srcImage = imagecreatefrompng($f_src);
	
		$srcW = ImageSX($srcImage);
		$srcH = ImageSY($srcImage);
		
		$ratioW = $newW ? $srcW/$newW : 1;
		$ratioH = $newH ? $srcH/$newH : 1;
		
		if($srcW <= $newH && $srcW <= $newW)
		{
			$destW = $srcW;
			$destH = $srcH;
		}	
		elseif ($ratioW < $ratioH) {
			$destW = floor($srcW/$ratioH);
			$destH = $newH ? $newH : $srcH;
		}
		else {
			$destW = $newW ? $newW : $srcW;
			$destH = floor($srcH/$ratioW);
		}
		$destImage = imagecreatetruecolor($destW, $destH);
		imagecopyresampled($destImage, $srcImage, 0, 0, 0, 0, $destW,
$destH, $srcW, $srcH);
		ImagePng ($destImage,$f_dest);
		ImageDestroy ($srcImage);
		ImageDestroy ($destImage);

		// now copy $f_dest to any place in DOCUMENT_ROOT...

I still haven't recieved an answer to the original question, but after
installing PHP 4.3.6, it works fine. Thank you for the help, check out
the site to see what I used it for.

Nevermind, I'm in the middle of developing some stuff, so don't check
out the site. I hope in the long run it will be larger, and you may
see the final product, which will be much more impressive than what is
available for viewing now.
