And this is the code I need to replace the tep image information.

// proper image ratio. Used in conjunction with product_thumb.php t/n generator.

// Set default image variable and code

$image = '<img src="' . $src . '"';

 

// Don't calculate if the image is set to a "%" width

if (strstr($width,'%') == false || strstr($height,'%') == false) {

$dont_calculate = 0;

} else {

$dont_calculate = 1;

}

 

// Do we calculate the image size?

if (CONFIG_CALCULATE_IMAGE_SIZE && !$dont_calculate) {

 

// Get the image's information

if ($image_size = @getimagesize($src)) {

 

$ratio = $image_size[1] / $image_size[0];

 

// Set the width and height to the proper ratio

if (!$width && $height) {

$ratio = $height / $image_size[1];

$width = intval($image_size[0] * $ratio);

} elseif ($width && !$height) {

$ratio = $width / $image_size[0];

$height = intval($image_size[1] * $ratio);

} elseif (!$width && !$height) {

$width = $image_size[0];

$height = $image_size[1];

}

 

// Scale the image if larger than the set width or height

if ($image_size[0] > $width || $image_size[1] > $height) {

$rx = $image_size[0] / $width;

$ry = $image_size[1] / $height;

 

if ($rx < $ry) {

$width = intval($height / $ratio);

} else {

$height = intval($width * $ratio);

}

 

$image = '<img src="product_thumb.php?img='.$src.'&w='.tep_output_string($width).'&h='.tep_output_string($height).'"';

}

 

} elseif (IMAGE_REQUIRED == 'false') {

return '';

}

}

 

// Add remaining image parameters if they exist

if ($width) {

$image .= ' width="' . tep_output_string($width) . '"';

}

 

if ($height) {

$image .= ' height="' . tep_output_string($height) . '"';

}

 

if ($params != '') {

$image .= ' ' . $params;

}

 

$image .= ' border="0" alt=" ' . tep_output_string($alt) . ' "';

 

if ($alt)

$image .= ' title=" ' . tep_output_string($alt) . ' "';

 

$image .= '>';

 

return $image;

}

 

 

I just don't know where I need to replace it.

I don't bother doing backups. I love the thrill of screwing it all up!
