image resize script probleempje!

..

Zet eens error_reporting(E_ALL); bovenaan je script.

Waarom niet een image class gebruiken die meteen wertk ...

<?php 
//class image handler
    class image
    {
	//only for image handlers
	var $supportim = array(1,2,3); //1 = gif / 2 = jpg / 3 = png 
	//check for file realy exists
	//$file = file that schould be resized / what ever
	function _check_file(){
		if(file_exists($this->file)){
			//file does realy exists
			return true;
		}else{
			return false;
		}
	}
	//recive image size and check if file is realy a image
	function _get_image_size(){
		if($this->dimension = getimagesize($this->file)){
			//we got a image;
			return true;
		}else{
			return false;
		}
	}
	//check if we got a support for those images
	function _check_image_support(){
		if(empty($this->dimension)){
			//trigger a error;
			trigger_error('No file specified please run get_image_size first',E_WARNING_ERROR);	
		}else{
		  if(in_array($this->dimension[2],$this->supportim)){

Beste R,
het is vaak handiger te beginnen met de 'simpele' PHP-tutorials dan te beginnen met een moeilijk script zonder basis.. :)
Ik hoop dat je wel een beetje beginselen van PHP hebt!
Verder include (roep je iets aan) met

include("Bestandsnaam.extensie");

sorry pik maar op zo een gare reactie zit ik niet te wachten,,, je maakt me hier een beetje belachelijk.... maargoed BESTE harmen....

ik denk dat ik maar eens ga "beginnen" met tutorials... dat is het beste wat ik kan doen toch?

dan hoef jij natuurlijk niet te brainstormen over mijn problemen.... daar krijg je zeker hoofdpijn van he?

ja sorry mijn fout om hier om hulp te vragen want daar is php hulp natuuurlijk niet voor.......... toch?
