Errors returned when gallery displayed on a page.

If I create a page with the following tag I get the following error message:

[bg|gallery/640x480|3|]

# notice: Undefined offset: 4 in /var/www/drupal/sites/all/modules/brilliant_gallery/brilliant_gallery.module on line 497.
# notice: Undefined offset: 5 in /var/www/drupal/sites/all/modules/brilliant_gallery/brilliant_gallery.module on line 497.
# notice: Undefined offset: 6 in /var/www/drupal/sites/all/modules/brilliant_gallery/brilliant_gallery.module on line 497.
# notice: Undefined offset: 7 in /var/www/drupal/sites/all/modules/brilliant_gallery/brilliant_gallery.module on line 497.
# notice: Undefined offset: 8 in /var/www/drupal/sites/all/modules/brilliant_gallery/brilliant_gallery.module on line 497.

All images in gallery/640x480 have been resized to 640 pixels x 480 pixels and are .JPG files

When I load the page using the above mentioned tag, the thumbnails render but I get the following error message for each image in the file (not displaying all as there are 60 images in the file)

# notice: Undefined index: imgwbig in /var/www/drupal/sites/all/modules/brilliant_gallery/brilliant_gallery.module on line 375.
# notice: Undefined index: imghbig in /var/www/drupal/sites/all/modules/brilliant_gallery/brilliant_gallery.module on line 376.
