This isn't a request for help, mearly for people looking for a simple way to do thumbnails without the actual thumbnail file.

It works via url for example thumbit.php?image=URL yes its ment to be used in a IMG tag.

PHP Code:
<?php

    
// Input
    
$s_image $_GET['image'];
    
$max_width 300;
    
$max_height 300;
       
$quality 75;

    
//Resizing and Output
    
if (preg_match("/.jpg/i""$s_image"))  {

    
header('Content-type: image/jpeg');
      list(
$width$height) = getimagesize($s_image);
    
$ratio = ($width $height) ? $max_width/$width $max_height/$height
    if(
$width $max_width || $height $max_height) { 
    
$new_width $width $ratio
    
$new_height $height $ratio
    } else {
    
$new_width $width
    
$new_height $height;
    } 
      
$image_p imagecreatetruecolor($new_width$new_height);
    
$image imagecreatefromjpeg($s_image); 
    
imagecopyresampled($image_p$image0000$new_width$new_height$width$height);
    
imagejpeg($image_pnull$quality); 
    
imagedestroy($image_p); 

    }
       elseif (
preg_match("/.png/i""$s_image"))  {

    
header('Content-type: image/png');
      list(
$width$height) = getimagesize($s_image);
    
$ratio = ($width $height) ? $max_width/$width $max_height/$height
    if(
$width $max_width || $height $max_height) { 
    
$new_width $width $ratio
    
$new_height $height $ratio
    } else {
    
$new_width $width
    
$new_height $height;
    } 
    
$image_p imagecreatetruecolor($new_width$new_height);
    
$image imagecreatefrompng($s_image); 
    
imagecopyresampled($image_p$image0000$new_width$new_height$width$height);
    
imagepng($image_pnull$quality); 
    
imagedestroy($image_p); 

    }
       elseif (
preg_match("/.gif/i""$s_image"))  {

      list(

    if(
$width $max_width || $height $max_height) { 
    
$new_width $width $ratio
    
$new_height $height $ratio
    } else {
    
$new_width $width
    
$new_height $height;
    } 
    
$image_p imagecreatetruecolor($new_width$new_height);
    
$image imagecreatefromgif($s_image); 
    
imagecopyresampled($image_p$image0000$new_width$new_height$width$height);
    
imagegif($image_pnull$quality);
    
imagedestroy($image_p); 

    }
       else {
