I wish I had found this months ago...great hack Z :)

However, I think the install .txt file may have gotten trunked somehow. This is all I am getting:

PHP Code:
This hack adds a new tag to your forums that will allow you to post images
in the form of a thumbnail.

The tag allows you to post pictures in the form of a thumbnail. Large images
can throw off the page, and the tag will scale the picture down to an 80x60
thumbnail preserving its original length and width ratio and turn it into a
hyperlink that you can click on and see the full image in a new browser window.
If the image being thumbnailed is smaller than 80x60, it will show up as is. 

This tag is identical to the IMG tag.

Tables affected: none
Templates affected: none
Files affected: admin/functions.php

Check out this link for a demo: [url]http://www.ls1.com/forums/showthread.php?s=&threadid=276879[/url]

*************************************************************************************
Note: This tag does not resize the actual picture. It just displays them at a smaller
      scale. It will not help with bandwidth preservation.
*************************************************************************************


In admin/functions.php
Look for:

        $bbcode=str_replace("{", "{", $bbcode); // stop people posting replacements in their posts

  return censortext($bbcode);

And change it to:

        $bbcode=str_replace("{", "{", $bbcode); // stop people posting replacements in their posts
        $bbcode=preg_replace("/\[thumb\](\r\n|\r|\n)*((http|https):\/\/([^;<>\(\)\"".iif($allowdynimg,"","!\*\?\&")."]+)|[a-z0-9\/\\\._\- ]+)\[\/thumb\]/esiU", "dothumb('\\2')", $bbcode);
  return censortext($bbcode);

########################################

In admin/functions.php

look for:

// ###################### Start phphighlite #######################

Add the following directly above it:

// ###################### Start dothumb #######################
function dothumb($code) {

  $img_info = @getimagesize($code);
  if($img_info[0]) {
    if(($img_info[0] <= 80) and ($img_info[1] <= 60)) {
      $code = "<a href=\"$code\" target=\"_blank\"><img src=\"$code\"></a>";
    }
    else {
      $xratio = $img_info[0] / 80;
      $yratio = $img_info[1] / 60;
      $factor = $xratio;
      if($yratio > $xratio) {
        $factor = $yratio;
      }
      $xsize = intval($img_info[0] / $factor);
      $ysize = intval($img_info[1] / $factor);
      $code="<a href=\"$code\" target=\"_blank\"><img src=\"$code\" width=\"$xsize\" height=\"$ysize\" border=\"3\"></a>";
    }
  }

  return($code);
} 
I did this and the tag isn't working...don't I have to add a BBcode via the admin control panel as well?

It is the complete file. That's all you need to do. No need to add anything through the admin CP. ;)

boutwell 04-08-2003 05:41 PM
Ok I am at a total loss here Zzed...are there any other hacks that this doesn't cooperate with with perhaps? Everything is set correctly but it still only shows the URL of the image I post for some reason.

Here is my test post:

http://dev.ringofdestiny.com/vb/show...php?threadid=2

Here is the contents of that post:

{thumb}http://205.214.94.176/~rod/images/emperor.jpg{/thumb} (with brackets of course)

If you are really bored I will mail you the info for my dev board and you can take a look :)

I worked with boutwell and we dicovered that his site is not able to get the length and width dimensions for certain pictures.

The dothumb() function tries to obtain the XY sizes for the picture and if it is not able to do it, it displays the URL for the picture...

This is how you can debug your code:

In functions.php

Look for:
PHP Code:
  $img_info = @getimagesize($code); 
And replace it with the following:
PHP Code:
  $img_info = @getimagesize($code);
  echo "$code <br>";
  echo "$img_info[0] <br>";
  echo "$img_info[1] <br>"; 
And you will notice that the length and width information show up blank.

If you want to bypass all the drama you can go the easy route and replace the function dothumb() with the following:
PHP Code:
 
function dothumb($code) {
 
  $code="<a href=\"$code\" target=\"_blank\"><img src=\"$code\" width=\"80\" height=\"60\" border=\"3\"></a>";
 
  return($code);
} 
Of course the only drawback with this is that if you try and thumbnail a smilie, it will actually magnify it. :)

Let me know if this helps...
