Very first thing: Invalid argument supplied for foreach()

[borism...@hotmail.com]

Hello
The very first thing after implementing camera slide show in a WP3.8.1 static page is
"Warning: Invalid argument supplied for foreach() in [...]/wp-content/plugins/camera-slideshow/lib/camera_functions.php on line 475"
Im not used to php, is there something I could fix without a lot of coding?
Thank you in advance
