Get image from php call help needed

[Starbuck2010]

when i attempt to call an image form this script, I just get the default value of an email based upon gender.

In order to avoid segfaults on a very busy site thats littered with images, i created a function that takes a userid, devides it by 100000, then devides it again by 4. While the uploading of the images work, i cant for the life of me get them to display in my smarty template.. Please help

<?php

	$userid = $_SESSION['UserId'];

You're asking the browser to prompt to download the image via the attachment header.

Just supply the proper image headers* and print the image. You would then include the image just like any other image, but pointing the image src to the PHP page instead of a jpg or whatever.

*i.e. header("Content-Type: image/jpeg");

Here is a simple captcha that is called via <img src="captcha.php" />

<?php
  session_start();

  // create a random string
  $md5_hash = sha1(md5(uniqid(null, true)));

  // create a 5 character security code
  $security_code = substr($md5_hash, 15, 5);

  $_SESSION['captcha_code'] = $security_code;

  // set width and height
  $width = 72;
  $height = 25;

  // create image
  $image = imagecreate($width, $height);

  $white = imagecolorallocate($image, 255, 255, 255);
  $black = imagecolorallocate($image, 0, 0, 0);

  // setup the image background
  imagefill($image, 0, 0, $black);

  // add string to the image
  imagestring($image, 3, 21, 7, $security_code, $white);

  imagerectangle($image,0,0,$width-1,$height-1,$grey);

  // setup the page headers
  header("Content-Type: image/jpeg");

  // output the image to the browser
  imagejpeg($image);
