New BB tag to do image thumbnails...

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. The new tag is THUMB

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

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

I don't know what it was but I tried it again and now it's working! Thank You! You are the master!

Now the only problem I can see is the images in the signatures, they're linked now, with a border, even after I changed border=1 to 0.

Thank you kind sir.

Please give me a link to a thread containing an image in the sig.

And I am so hurt that you deleted my replies... :laugh::banana:

Sorry about that, just part of the testing process

That's because the image is 256x170 which is smaller than your 320x240 image resize.

in dothumb()

Replace this:

    if(($img_info[0] <= 80) and ($img_info[1] <= 60)) {
      $code = "<a href=\"$code\" target=\"_blank\"><img src=\"$code\"></a>";
    }

with this:

    if(($img_info[0] <= 80) and ($img_info[1] <= 60)) {
      $code = "<a href=\"$code\" target=\"_blank\" border=\"0\"><img src=\"$code\"></a>";
    }

Excpet that instead of 80 and 60 you would be using 320 and 240 in the if statement.

[Katman]

I did that originally.

Forget it, I see, Duh, you added the border=0

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

  $img_info = @getimagesize($code);
  if($img_info[0]) {
    if(($img_info[0] <= 320) and ($img_info[1] <= 240)) {
      $code = "<a href=\"$code\" target=\"_blank\"><img src=\"$code\"></a>";
    }
    else {
      $xratio = $img_info[0] / 320;
      $yratio = $img_info[1] / 240;
      $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=\"0\"></a><br><font size=\"-2\">(click for larger image)</font>";
    }
  }

  return($code);
}
// ###################### End dothumb #######################

Cool.

[Katman]

Nope, still linked with border. I'm going to add border=\"0\" to every href tag!

Damn, still there.

Got it! Needed to add border=0 to

<img src=\"$code\" border=\"0\"></a>";

Nope, just hit reload. The border will go away.

[Katman]

OK, I'm done now, it's all good! Thanks for the quick helpful replies!

[Zzed]

You're very welcome.

Hmm, I don't know why the PHP tag mutilated my preg_replace statement.

I have tried this on my board and it worked just fine.

$bbcode =  preg_replace("/img\]/i", "thumb]", $bbcode);

Didnt work for me, showed the image as a link rather than a thumbnail
