Rough code of "index.php":



<?php

if ($dh = opendir('./images')) (
$files = array();
while (($file = readdir($dh)) !== false) (
if ($file !== "." && $file !== ".." && $file !== "index.html") (

array_push($files, $file);
)
)
closedir($dh);
)

$index = array_rand($files);
$extension = pathinfo($files[$index]);
$extension = $extension['extension'];

if ( $extension == "jpg" ) (
header("Content-type: image/jpeg");
imagejpeg(imagecreatefromjpeg("images/".$files[$index]));
)

if ( $extension == "png" ) (
header("Content-type: image/png");
imagepng(imagecreatefrompng("images/".$files[$index]));
)

if ( $extension == "gif" ) (
header("Content-type: image/gif");
echo file_get_contents("images/".$files[$index]);
)

if ( $extension == "bmp" ) (
header("Content-type: image/bmp");
imagebmp(imagecreatefrombmp("images/".$files[$index]));
)

?>

Requires a readable image directory in same directory as "index.php" entitled "images".

Posting the above resulted in braces being changed to parenthesis. So... one more time:



<?php


if ($dh = opendir('./images')) "
$files = array();
while (($file = readdir($dh)) !== false) "
if ($file !== "." && $file !== ".." && $file !== "index.html") "

array_push($files, $file);
>
>
closedir($dh);
>

$index = array_rand($files);
$extension = pathinfo($files[$index]);
$extension = $extension['extension'];

if ( $extension == "jpg" ) "
header("Content-type: image/jpeg");
imagejpeg(imagecreatefromjpeg("images/".$files[$index]));
>

if ( $extension == "png" ) "
header("Content-type: image/png");
imagepng(imagecreatefrompng("images/".$files[$index]));
>

if ( $extension == "gif" ) "
header("Content-type: image/gif");
echo file_get_contents("images/".$files[$index]);
>

if ( $extension == "bmp" ) "
header("Content-type: image/bmp");
imagebmp(imagecreatefrombmp("images/".$files[$index]));
>

?>

Again, posted is not equal to previewed so... one more time:



<?php


if ($dh = opendir('./images')) "
$files = array();
while (($file = readdir($dh)) !== false) "
if ($file !== "." && $file !== ".." && $file !== "index.html") "

array_push($files, $file);
>
>
closedir($dh);
>

$index = array_rand($files);
$extension = pathinfo($files[$index]);
$extension = $extension['extension'];

if ( $extension == "jpg" ) "
header("Content-type: image/jpeg");
imagejpeg(imagecreatefromjpeg("images/".$files[$index]));
>

if ( $extension == "png" ) "
header("Content-type: image/png");
imagepng(imagecreatefrompng("images/".$files[$index]));
>

if ( $extension == "gif" ) "
header("Content-type: image/gif");
echo file_get_contents("images/".$files[$index]);
>

if ( $extension == "bmp" ) "
header("Content-type: image/bmp");
imagebmp(imagecreatefrombmp("images/".$files[$index]));
>

?>

A simple upload script to place images in the image directory.
Probably rough, I'm no programmer. It seems to work though.

Because of the way "header" works, that opening php tag absolutely has to be on the very first line, very first character.

I kinda knew, but kinda didn't. I just had to debug because I had added a blank line at the top and pushed it one character right to make it easier to do an area screen capture. :)

That should probably be guarded against, at least if it works the same for the title of the original post. There would be no way for the average user to even click into the thread, no way to reply, no way it would ever sink. Maybe it wouldn't work like that in the main title, still... I would be afraid to try it to find out. :)
