Error on Page / Virtual Template = image

Hello,

Getting an error when I view a page Page where I have used the Virtual Page / image option.

Error is as follows:

Warning: array_keys() expects parameter 1 to be array, string given in /home/fordgr5/public_html/tisdall.org/wp-content/themes/montezuma/includes/image_meta.php on line 34

Warning: Invalid argument supplied for foreach() in /home/fordgr5/public_html/tisdall.org/wp-content/themes/montezuma/includes/image_meta.php on line 40

See base of this page:

Any ideas?

Thanks!
