On the fly contribution

The Criteria · January 22, 2005

The installation instructions say:

Then find the "tep_image" function in the
"includes/functions/html_output.php" file and replace it with the code at the bottom

of this document.

I don't know what code needs to be changed. I tried several times to no avail, I have been searching posts for nearly two days, and still no luck. Please help me. Also, are there any other contributions I need to make this one work?

I don't know how much of the code is the "tep_image function". Any help?

<{POST_SNAPBACK}>

Can someone help me out? Am I posting this in the wrong category or something?

Please do not post an entire screen full of code!

To answer your questions:

A function definition (which is what you're looking for) looks like this:

function my_function($a, $b, $c=0){

code code code code

}

This function is called my_function. It needs arguments $a and $b when you use it, and you can pass in argument $c if you need, otherwise $c will be 0. Notice the placement of the parenthesis () and the braces {} in the function.

This is the tep_image function:

function tep_image($src, $alt = '', $width = '', $height = '', $parameters = '') {

if ( (empty($src) || ($src == DIR_WS_IMAGES)) && (IMAGE_REQUIRED == 'false') ) {

return false;

}

Assalaamu walaikum

I downloaded the contribution you are having problems with (as I do not use that to manage my images)...

First off, I recommed downloading a program called TextPad (much better and many features for editing your files)

Also Backup your file to have original file to revert to if problems arise Inshallah.

Now around line 73 - 113 .. or look for this code:

// The HTML image wrapper function

Right after that is what you will change...this is what you look for to replace:

// The HTML image wrapper function
 function tep_image($src, $alt = '', $width = '', $height = '', $parameters = '') {
   if ( (empty($src) || ($src == DIR_WS_IMAGES)) && (IMAGE_REQUIRED == 'false') ) {
     return false;
   }

// alt is added to the img tag even if it is null to prevent browsers from outputting
// the image filename as default
   $image = '<img src="' . tep_output_string($src) . '" border="0" alt="' . tep_output_string($alt) . '"';

   if (tep_not_null($alt)) {
     $image .= ' title=" ' . tep_output_string($alt) . ' "';
   }

   if ( (CONFIG_CALCULATE_IMAGE_SIZE == 'true') && (empty($width) || empty($height)) ) {
     if ($image_size = @getimagesize($src)) {
       if (empty($width) && tep_not_null($height)) {
         $ratio = $height / $image_size[1];
         $width = $image_size[0] * $ratio;
       } elseif (tep_not_null($width) && empty($height)) {
         $ratio = $width / $image_size[0];
         $height = $image_size[1] * $ratio;
       } elseif (empty($width) && empty($height)) {
         $width = $image_size[0];
         $height = $image_size[1];
       }
     } elseif (IMAGE_REQUIRED == 'false') {
       return false;
     }
   }

   if (tep_not_null($width) && tep_not_null($height)) {
     $image .= ' width="' . tep_output_string($width) . '" height="' . tep_output_string($height) . '"';
   }

   if (tep_not_null($parameters)) $image .= ' ' . $parameters;

   $image .= '>';

   return $image;
 }

... Replace the above code with:

// "On the Fly Thumbnailer" using PHP GD Graphics Library by Nathan Welch (v1.5)
// Scales product images dynamically, resulting in smaller file sizes, and keeps
// proper image ratio.  Used in conjunction with product_thumb.php t/n generator.
function tep_image($src, $alt = '', $width = '', $height = '', $params = '') { 

   // 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; 
}

The way I manage my images is very simple in my opinion. I manually adjust my images (compress, check file size, etc) and I add my 'Thumbnail' picture using the admin panel ..(adding product like normal)..

..but I them upload my own 'larger image' that I have adjusted to another folder I created called 'larger' ...

That way both images are the way I intended them to appear. This requires some skill using graphics program as well as time to upload the larger image, but I like it. I also fixed the problem I had with (as far as I know) browser on systems with xp service pack 2 cutting off the bottom of the popup larger image ...

Now, as far as storage, does this take up a lot more space on the server? What program do you use to resize your images and will the process work with different size and/or shaped images (i.e. square and rectangular)
