Calling an image - Page 2

A few quick questions that would truly help me complete a project i'm working on.

I have the following script that generates an image. The script works great, but heres where I'm stuck:

I need to call the image it generates from an HTML file. So, in that file I'm unsure on how to tell the script to execute and then go out and grab the generated image.

PHP Code:


			
<?php

resize("./", "http://images.wsdot.wa.gov/nwflow/flowmaps/sysvert.gif", "538", "./");

function resize($cur_dir, $cur_file, $newwidth, $output_dir)

{

    $dir_name = $cur_dir;

    $olddir = getcwd();

    $dir = opendir($dir_name);

    $filename = $cur_file;

    $format='image/gif';

    if(preg_match("/.jpg/i", "$filename"))

    {

        $format = 'image/jpeg';

    }

    if (preg_match("/.gif/i", "$filename"))

    {

        $format = 'image/gif';

    }

    if(preg_match("/.png/i", "$filename"))

    {
