Assuming you are using vbadvanced and you want it to use in a module..
Make a PHP module for vbadvanced using the following code
else
delete the footer for eval template, save as a phpfile index.php and place this in the directory with pictures and call it from the template mentioned below then iframe to the index.php file
<?php
#$imagedir is the directory that holds your images.
#Be SURE to include the trailing slash in the name.
$imagedir = "../../images/chicks/";
################################################## #######
#Editing below is not required. #
################################################## #######
$images = array();
#Locate and all of the existing images
$directory = opendir($imagedir);
while($filename = readdir($directory)){
if(strlen($filename) > 2){ #ignore . and ..
$localext = substr($filename, -3);
if(!((strcasecmp($localext, "gif") == 0) || (strcasecmp($localext, "jpg") == 0) || (strcasecmp($localext, "bmp") == 0) || (strcasecmp($localext, "png") == 0)))
continue;
array_push($images, $filename);
}
}
#choose a random image from the array
srand((double)microtime() * 1000000);
$selection = $images[rand(0, sizeof($images)-1)];
#display the image
echo "<img src=\"$imagedir$selection \" alt=\"$selection (" . filesize("$imagedir/$selection") . " bytes)\">";
eval('$home[$mods[\'modid\']][\'content\'] .= "' . fetch_template('adv_portal_randomchickblock') . '";');
?>
This one works with .bmp,.gif,.jpg and png files
Make sure that you use the correct path and at the bottom of this script we call a template 'adv_portal_randomchickblock' but you can use whatever name you like ofcourse..
I had this running on several sites for years
good luck
