    if ($config['auto_image'] && !$uploaderror)
    {
      if ($direct_upload)
      {
        $src = MEDIA_PATH."/".$cat_id."/".$new_name;
      }
      else
      {
        $src = MEDIA_TEMP_PATH."/".$new_name;
      }
      $do_resize = 0;
      if ($image_info = @getimagesize($src))
      {
        if ($image_info[2] > 0 && $image_info[2] < 4 && $image_info[0] > $config['max_image_width'] || $image_info[1] > $config['max_image_height'])
        {
          if (!function_exists("init_convert_options"))
          {
            require(ROOT_PATH.'includes/image_utils.php');
          }
          $convert_options = init_convert_options();
          if (!$convert_options['convert_error'])
          {
            $quality = intval($config['auto_image_quality']);
            $quality = ($quality >= 0 && $quality <= 100) ? $quality : 85;
            if (!resize_image($src, $quality, $config['max_image_width'], 1, $config['max_image_height']))
            {
              $msg .= (($msg != "") ? "<br />" : "")."<b>".$lang['file_upload_error'].": ".$new_name;
              $uploaderror = 1;
            }
          }
        }
      }
    }
    if ($config['auto_thumbnail'] && !$uploaderror)
    {
      if ($direct_upload)
      {
        $src = THUMB_PATH."/".$cat_id."/".$new_name;
      }
      else
      {
        $src = THUMB_TEMP_PATH."/".$new_name;
      }
      $do_resize = 0;
      if ($image_info = @getimagesize($src))
      {
        if ($image_info[2] > 0 && $image_info[2] < 4 && $image_info[0] > $config['max_thumb_width'] || $image_info[1] > $config['max_thumb_height'])
        {
          if (!function_exists("init_convert_options"))
          {
            require(ROOT_PATH.'includes/image_utils.php');
          }
          $convert_options = init_convert_options();
          if (!$convert_options['convert_error'])
          {
            $quality = intval($config['auto_image_quality']);
            $quality = ($quality >= 0 && $quality <= 100) ? $quality : 85;
            if (!resize_image($src, $quality, $config['max_thumb_width'], 1, $config['max_thumb_height']))
            {
              $msg .= (($msg != "") ? "<br />" : "")."<b>".$lang['file_upload_error'].": ".$new_name;
              $uploaderror = 1;
            }
          }
        }
      }
    }
//--- End Auto Image Resizing ----------------




Step 2
Open /includes/upload.php

Find:

Code: [Select]

   $this->max_height['media'] = $config['max_image_height'];
Insert _below:

Code: [Select]

   $this->auto_image['media'] = $config['auto_image'];
    $this->auto_image['thumb'] = $config['auto_thumbnail'];


Step 2.2
Find:

Code: [Select]

   $this->image_size = @getimagesize($this->upload_file);
    $ok = 1;
Insert _below:

Code: [Select]

    if ($this->auto_image[$this->image_type]) {
      return 1; //auto image is on, don't need check for anything else.
    }




Step 3
Open /admin/settings.php

Find:

Code: [Select]

 show_setting_row("upload_emails");
Insert _below:

Code: [Select]

 show_setting_row("auto_image", "radio");
  show_setting_row("auto_image_quality");



Step 4
Open /lang/<yourlanguage>/admin.php

Find:

Code: [Select]

$setting['auto_thumbnail_quality'] = "Thumbnail quality<br /><span class=\"smalltext\">0 to 100</span>";
Insert _below:

Code: [Select]

$setting['auto_image'] = "Auto-resize image";
$setting['auto_image_quality'] = "Auto-resize image quality";



Step 5
Download attached file below.

Unzip it and upload to your 4images ROOT dir.
Execute it http://yoursiteaddress/4images/install_autoimage.php




Step 6
Go to Admin Control Panel -> settings. Under Upload settings u should find new options. Make sure "Max. image size in KB" is set to a high enough number




Step 7
This step u'll need only if u installed MOD Annotation by SLL
All u need to do is move code of Annotation, that u added in member.php, move it below the code u added in Step 1


Step 8 (Added 19/09/04)
This is an optional step, u'd need it if u want resize images not only using max width value as dimention but also max height.
Install atleast Step 1.x from this fix:
[FIX] Max height has no affect when do image resize

[knuckles]

/home/virtual/site56/fst/var/www/html/platinum/gallery/admin/settings.php on line 311

Line 311 is: show_setting_row("auto_image_quality");

But it looks fine, it must be cascading from somewhere else.

[knuckles]

Had to write the following two lines by hand:

show_setting_row("auto_image", "radio");
show_setting_row("auto_image_quality");

one of them had/has hidden chars that where affecting the script.

Thanks!

This MOD will resize uploaded by users images to Max. Image Width set in settings.

Question:

I'm assuming this means it will scale down images that exceed the width/height setting and not scale up images that are smaller than the settings.  

Is this correct?

[V@no]

yes, that's correct, the script checks first if image bigger then max width or height, then resize it if so.

[SLL]

Very good idea, V@no! According to my experience, just 10% of users have some idea how to resize their images, so if they're trying to upload oversized photos, and gallery doesn't accept it, they just give up...

Hallo V@ano,

I have an error message. This error is not always. Mostly with large pictures.

Warning: imagecreatefromjpeg: './data/media/4/168-6875_IMG.JPG' is not a valid JPEG file in /homepages/8/d13361873/htdocs/digitalfotograf/bilderkiste/includes/image_utils.php on line 71


Warning: imagecreatefromjpeg: './data/media/4/168-6875_IMG.JPG.bak' is not a valid JPEG file in /homepages/8/d13361873/htdocs/digitalfotograf/bilderkiste/includes/image_utils.php on line 71


Here cut out of the lines 67 - 75:

else {
    $thumb = imagecreate($width, $height);
  }
  $image_create_handle = "imagecreatefrom".$types[$image_info[2]];
  if ($image = $image_create_handle($src)) {
    if (defined('CONVERT_IS_GD2') && CONVERT_IS_GD2 == 1) {
      imagecopyresampled($thumb, $image, 0, 0, 0, 0, $width, $height, ImageSX($image), ImageSY($image));
    }
    else {


Do you have a solution for the problem?

CU Ingo.

I am getting the same error too ... Although installed the mod but cannot work ... it seems that any thing that deals with converting of images .. there is a problem between windows and unix ...

can u do any image manipulations from admin control panel? if not, then ask your host what wrong, it's really nothing to do with the script itself.

Hi V@no,

do you sleep also sometime?  :

I forgot to post today that I did not turned the "auto-resize-function" on in admin menu. I guess this was the reason for the error code above from 26.2.2003, since it disappeared...

So the current status is the one of this morning in the other thread. It resizes automatically the images, which exceed the max. restriction in the admin-menu.

But as far as I remember it just looks at the width restriction, not at the height restriction.

Dirk

Is there such a function to turn on in the admin menu? I cannto find the auto resize function ...

[V@no]

if u can not find that in the settings, then, no wonder it doesnt work....
check again step-by-step instructions.
