controlling image size...

[Damascus]

How would I keep images proportional, but never have a width over 115px or a height over 100px? Just look at this site:

http://stock.d2.hu/index.phtml?f=s&c=101

Here is the code I'm trying to work with:

			$dim = getimagesize($pics[$i]);

		if($dim[0] > $config['max_width'] || $dim[1] > $config['max_height']){

			if($dim[0] > 115){

				$width = 115;

			}else{

				$width = $config['max_width'];

			}

			if($dim[1] > 100){

				$height = 100;

			}else{

				$height = $config['max_height'];

			}

			$image = "<img src='{$pics[$i]}' width='{$width}' height='{$height}' border='0'>";

		}else{

			$image = "<img src='{$pics[$i]}' border='0'>";

		}

Could someone gimme a quick hand?🙂

Try integrating this script:

$max = 100;
if ($pics == "") {} else {
$imagehw = getimagesize($pics); 
    $imagewidth = $imagehw[0]; 
    $imageheight = $imagehw[1]; 
	if (($imageheight > $max) || ($imagewidth > $max)) 
  {   

    if ($imageheight > $imagewidth) 
    { 
      $sizefactor = (double) ($max / $imageheight);
    } 
    else 
    {
      $sizefactor = (double) ($max / $imagewidth) ;
    }
  }    

  $newwidth = (int) ($imagewidth * $sizefactor);
  $newheight = (int) ($imageheight * $sizefactor); 
  if (($newheight == "0") || ($newwidth == "0")) {
  $heightwidth = "";
  }else{
  $heightwidth = "height=".$newheight." width=".$newwidth;
  }
  }

Thanks for the helping hand, broseph! Here is my ported code:

			$wmax = $config['max_width'];

		$hmax = $config['max_height'];

		$dim = getimagesize($pics[$i]); 

		if (($dim[1] > $hmax) || ($dim[0] > $wmax)) {   

			if ($dim[1] > $dim[0]) { 

				$sizefactor = (double) ($hmax / $dim[1]);

			} else {

				$sizefactor = (double) ($wmax / $dim[0]) ;

			}

		}  

		$newwidth = (int) ($dim[0] * $sizefactor);

		$newheight = (int) ($dim[1] * $sizefactor); 

		if (($newheight == "0") || ($newwidth == "0")) {

			$heightwidth = "";

		}elseif($newheight < $hmax && $newwidth < $wmax){

			$heightwidth = "height=".$dim[1]." width=".$dim[0];

		}else{

			$heightwidth = "height=".$newheight." width=".$newwidth;

		}

		$image = "<img src='{$pics[$i]}' {$heightwidth}>";

where $config[max_height] and max_width = 100px & 115px respectively.

Works great!
