I have found a script which can be very usefull for your website.
The following MOD looks like "random-image" on your gallery but it works with your gallery-banner
Each refresh on your page loads new banner with different urls -> you can try this here
http://www.snuup.de/lite1. Create a new file e.g. banner_2006.php and paste this code into it -> save it in root of 4images gallery
1b. Define the path of $base_dir & $img_url

?>2. Create a new folder templates/default/images/banner
3. Create a new txt file called banner_405x60.txt and paste this line into it
# URL | target="_blank" (1 = Yes, 0 = No) | off-site image (1 = Yes, 0 = No) | image | Alt text4. Now you can add your banner and define url, target, image,... (off-site image 1 -> image is remote linked)
# URL | target="_blank" (1 = Yes, 0 = No) | off-site image (1 = Yes, 0 = No) | image | Alt text

Note: If you have installed other MODs - you have also edit these "TopLevel PHP" files!
Search in every file which is listed above:

Find:
<img src="{template_url}/images/header_logo.gif" width="405" height="60" alt="" />Replace:
<?php
echo get_banner("405x60");
?>If you have installed a Template from Bali-Webdesign you have only edit header.html
*when you have installed this mod
The positive effect of this script is that you can call banner with different sizes with the same banner_2006.php
e.g.
<?php
echo get_banner("88x31");
?>Now I hope I´ve nothing forget to explain! Good luck!
