for example

They are 3 images
1 w:100 h:80
2 w:90 h:100
3 w:120 h:70

and you want to have max width 100 and max height 80
1 - its OK
2 - to hight
3 - to wide

yu can add into

function.html_image.php
in switch before $$_key = $_val; :

Code:

case 'maxwidth':
case 'maxheight':

before return this code

Code:

if(isset($params['maxwidth'])) {
   if($width>$params['maxwidth']){
      $height =round($params['maxwidth'] * $height / $width);
      $width=$params['maxwidth'];
   }
}
if(isset($params['maxheight'])) {
   if($height>$params['maxheight']){
      $width =round($params['maxheight'] * $width / $height);
      $height=$params['maxheight'];
   }
}

and now you can write
{html_image file="$image" maxheight="50" maxwidth="50"}

These pictures whith are to hight or to wide become resize

i know this is wery siple exaple but it can be useful

ps. I apologize for my english
