Code:: <?php

$folder = '.';

$extList = array();
$extList['gif'] = 'image/gif';
$extList['jpg'] = 'image/jpeg';
$extList['jpeg'] = 'image/jpeg';
$extList['png'] = 'image/png';

$img = null;

if (substr($folder,-1) != '/') {
$folder = $folder.'/';
}

if (isset($_GET['img'])) {
$imageInfo = pathinfo($_GET['img']);
if (
isset( $extList[ strtolower( $imageInfo['extension'] ) ] ) &&
file_exists( $folder.$imageInfo['basename'] )
) {
$img = $folder.$imageInfo['basename'];
}
} else {
$fileList = array();
$handle = opendir($folder);
while ( false !== ( $file = readdir($handle) ) ) {
$file_info = pathinfo($file);
if (
isset( $extList[ strtolower( $file_info['extension'] ) ] )
) {
$fileList[] = $file;
}
}
closedir($handle);

if (count($fileList) > 0) {
$imageNumber = time() % count($fileList);
$img = $folder.$fileList[$imageNumber];
}
}
if ($img!=null) {
$imageInfo = pathinfo($img);
$contentType = 'Content-type: '.$extList[ $imageInfo['extension'] ];
header ($contentType);
readfile($img);
} else {
if ( function_exists('imagecreate') ) {
header ("Content-type: image/png");
$im = @imagecreate (100, 100)
or die ("Cannot initialize new GD image stream");
$background_color = imagecolorallocate ($im, 255, 255, 255);
$text_color = imagecolorallocate ($im, 0,0,0);
imagestring ($im, 2, 5, 5, "IMAGE ERROR", $text_color);

so your guys sites different the the 7forums i use this in i will try to figure a way for it to work sorry for the dely

Subject: Re: PHP Random Sig Wed Mar 05, 2008 10:53 am

hah yeah, HTML doesnt work in the sigs...a .php extension probably wouldnt work either. Someone sent me another way to do it i might post up that involved using a folder named something like image.jpg and so when it was requested, since it was a folder it would grab the index.php in the folder by default which had the script in it. I will try it and see if it works as i keep forgetting to do it.

For the guys that arnt server side script knowledgable too, this requires web hosting to do this...you cant just copy and paste the code to your sig or whatever. It requires a server running PHP that reads the php code and then gives your browser the output.

well thats the strange thing on our forum's(BiC which is phpbb) it works fine with html and .php

Subject: Re: PHP Random Sig Wed Mar 05, 2008 10:58 am

it likely has HTML enabled. Either they cant activate it due to it being hosted by a free thing or they just dont have it turned on. I believe it is actually off in most forums by default.

hmmm i see, well ok w/e, also if you guys ever need somewere to host stuff(forums,images,etc.) let me know i have a 1.5 TB server of which im using 1.2 gb lol

please ignore this tutorial unless you see a image below the code, in order for it to work here HTML will have to be enabled so if that happens that last line will have a picture that changes when the page is refreshed. sorry i did not notice HTML had been turned off before posting this. however if you like you can still use this in other forums that have HTML turned on.
