Random Image Format
Just like what it sounds like, it shows one random image - from the set of what you upload. Often used for the first page of the site, without text.
There are image size adjustments available on the Exhibit Options Dialogue Box.This image format does not show Image Titles and Captions. If you want it to do this:
$s .= "<img src='" . $OBJ->vars->images[$rand]['media_path'] . "' /> <p class='random_img_title'>" . $OBJ->vars->images[$rand]['media_title'] . "</p>";
