Random image script - El Forum - 02-14-2008
[eluser]Joe_Archer[/eluser]
Hi, I'm fairly well versed with CI and have been using it for around a year, successfully, both inside and outside of work.
As a little side project I'd like to produce a random image script which when called, selects an image from a folder at random and returns it to the browser.
I don't have a problem writing the code to do this, it's very straight forward, what I'm not sure about though, is how to return "just an image" to the browser. I don't want to output any HTML, I just want to return an image file as though the file had been browsed to directly on the server. I assume I'll need to set a mime type/header to do this, but I'm not sure how I'd go about doing so.
Any help greatly appreciated.

you need to write an independent script for this to work.
Code:
<?php
$path = $_GET['path'];
/*
* random code
*/
header('Content-type: '.$contenttype);
header('Content-Disposition: attachment; filename="'.$filename.'"');
readfile($filepath);
?>
To make a helper function out of this you do as follows
Code:
function random_image($path)
{
include('random_image.php?path='.$path);

I ended up doing it thus:
Code:
<?php
class Randomimage extends Controller{
function Randomimage(){
parent::Controller();
$this->load->helper('file');
}
function index(){
$path = '/path/to/image/folder/';
$filenames = get_filenames($path);
$key = array_rand($filenames);
$image = $filenames[$key];
Header("Content-Type: image/jpg");
readfile($path.$image);
}
}
?>I didn't need any independent scripts in the end.
