Help! Having Problem Trying To Install Auto Thumbnail Contribution

Azure Moon · January 5, 2007

Hi,

A total and complete clueless newbie here, so please be kind and use laymen's terms

I'm attempting to install the Automatic Thumbnail contribution, but for the life of me, I cannot find the line of code in my catalog/includes/functions/html_output.php file that I need to start with.

In step one, the contribution says to search for:

search for

# function thumbimage ($image, $x, $y, $aspectratio, $resize, $cachedir){

I've searched that file and I don't see that specific line anywhere. I'm hoping that I've just gone cross eyed and someone can help me.

Any further help will be greatly appreciated and will certainly save my few remaining brain cells...LOL.

Brightest Blessings,

Azure Moon

Here's a copy of my html_output.php file:

Thats only an update :), it assumes you already have Auto Thumbnailer installed. Go down in the install instructions for the full install details.

Hi Bob,

Thanks for you reply. I'm a total newbie...this is my first website. I purchased it pre-built and I'm pretty much clueless as far as all of this stuff is considered. I have no idea how to install anything.

Can you, or someone, give me step by step instructions as to how to install a Thumbnail contribution and exactly which is the best one to install?

I apologize for my ignorance, but as I said, I'm just starting out and all of this is Greek to me.

Brightest Blessings,

I'm not sure which is the best as I haven't used it, so I'll just repost the instructions here:

Installing should be quite easy, only one file to change.

Follow these 6 steps:

1. Open the File: /catalog/includes/functions/html_output.php

2. Search for: (~ Line 73)

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

3. Insert the following after it:

	if ($image_size = @getimagesize($src)) {
  if ((CONFIG_CALCULATE_IMAGE_SIZE == 'true' && $src != DIR_WS_IMAGES . 'pixel_black.gif' && $src != DIR_WS_IMAGES . 'pixel_trans.gif' && $src != DIR_WS_IMAGES . 'pixel_silver.gif' )) {
	if ( ($width) || ($height) ) {
		if ( $width=="100%" ) {
		  $width = $image_size[0];
		} elseif ( $height=="100%" ) {
		  $height = $image_size[1];
		} elseif ( $width==0 ) {
		  unset($width);
		} elseif ( $height==0 ) {
		  unset($height);
		}
		$src=thumbimage(DIR_FS_CATALOG . '/' .$src, $width, $height, 1, 1, DIR_FS_CATALOG . '/' . DIR_WS_IMAGES . 'imagecache');
		if ((($image_size[1]/$height) > ($image_size[0]/$width) ) && $height>0){
			 $width=ceil(($image_size[0]/$image_size[1])* $height);
		} elseif ($width>0) {
			 $height=ceil($width/($image_size[0]/$image_size[1]));
		}
	}
	  }
  } elseif (IMAGE_REQUIRED == 'false') {
	return '';
  }

4. Search for this and delete it:

	  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;
	}
  }

5. Go to the bottom of the File and insert before the ?>

function thumbimage ($image, $x, $y, $aspectratio, $resize, $cachedir){

define(JPEGQUALITY, 95); //define the quality of JPG thumbnails

Hi Bob,

Thank you so much! So you don't have this installed on your site? Are you sure it works? Just want to be sure before I change anything. Please advise.

Nope, I have something else installed, called ImageMagic. I think they're both the same thing, except that with ImageMagic, you have more control over what your outputted thumbs and images will be. Control over quality, dimensions, color, and so on. Not as easy to install though, because you'll need to edit several files.

If you want to try it out, here's the link:

http://www.celtware.com/im/

Just take your time to read the instructions very carefully :).
