I am stumped, this works fine when I run it from the Processing application, it works fine when I run it as an exported application. Yet in neither firefox or IE will it run as an applet.

PImage a;
int y = year();
int m = month();
int d = day();
String ds;
String ms;

void setup(){
 size (200,300);
}
void draw(){
 ms = str(m);
 ds = str(d);
 datecheck();
 loadimage();
 image (a,0,0);
}

void datecheck(){
 if (d<10){
   ds = ("0" + str(d));
 }
 if (m<10){
   ms = ("0" + str(m));
 }
}

void loadimage(){
 a = loadImage("http://www.telegraph.co.uk/news/graphics/"+y+"/"+ms+"/"+ds+"/matt.gif");
}

It's cross-site security that's tripping you up - running from google, loading from telegraph.  To make it work, you'd need to either have both applet and images in the same domain, or use some sort of server-side script (asp, php, etc) to fetch the offsite image for you and feed it back to your applet so that it *looks* like it came from the same domain.  Something like:

loadImage("http://mydomain.com/fetch.asp?http://offsite.com/image.jpg");

Thanks for the reply I'll have a look into it
Any help on the redirecting would be much appreciated

This seems to be what I am looking for but I am incapable of getting it to work

no. sending a header(location: .. ) will tell java to redirect it's call to the other location and this will fail again. what you need to do is "tunnel" the image thru php:

php
Code:

<?php
echo @readfile( $_GET['url'] );
?>


processing
Code:

PImage img;

void setup ()
{
    img = loadImage("readfile.php?url=http://processing.org/img/processing_beta_cover.gif");
}

void draw()
{
    image( img, 0,0 );   
}
