[SOLVED] picture resize function only works at times? memory issue? I dunno

[spdwrench]

I am using a function I just downloaded to resize and brand some text to an image...

 

I was so happy I finally got this working... but after repeated tries it started failing.... would not return the resized image.... I dont think it is setup to show me an error as to why..... anyway it was resizing any image greater than 800 x 600

 

and then putting my site title on the top of the image in white text...

 

this all works so well but only works intermitantly.... I actually had the same picture work one time but not the next...

 

Am I running out of memory somewhere? is there an image not being destroyed somewhere? causing a memory issue? my php memory is set to 32M (is that enough? I would think so)

 

here is the page that calls the function

 

<?php

//resize if too big + watermark
// call to function $file_source is the location of the upload file $size is the original size of uploaded file...
include("engine/ImageEditor.php"); 
if ($size[0] > $max_image_width||$size[1]>$max_image_height)
               {
$imageEditor = new ImageEditor($file_source, "photos/");
if ($size[0]>$size[1]){$imageEditor->resize(800,600);
$dtw=30;}
else {$imageEditor->resize(450,600);
$dtw=17;}
$imageEditor->outputFile($file_source, "photos/");

}
// text follows

if($dtw==0){$dtw=($size[0]/25);}
$imageEditor = new ImageEditor($file_source, "photos/");
$imageEditor->setFont("engine/pages/georgia.ttf");
$imageEditor->setSize($dtw);
// Following line is text going on picture starting position 50 x 10 y color white 255 255 255
$imageEditor->addText("ABMATCH.COM FREE DATING",10	, 50,array (255,255,255));
$imageEditor->outputFile($file_source, "photos/");
$dtw=0;
   
  
  
// End resize image and watermark
?>

 

 

the function being called by this bit of code is below:

 

<?php


class ImageEditor {
  var $x;
  var $y;
  var $type;
  var $img;  
  var $font;
  var $error;

it worked a couple times then started acting up and not producing a resized image....

 

My smile came right off my face
