Help deciphering errors

I just activated ExZo and accepted the default settings.
Here’s what I got:
Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: gd-jpeg: JPEG library reports unrecoverable error: in /home/content/07/10456907/html/wp-content/plugins/exzo/exzo.php on line 238

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: ‘/home/content/07/10456907/html/wp-content/plugins/exzo/images/’ is not a valid JPEG file in /home/content/07/10456907/html/wp-content/plugins/exzo/exzo.php on line 238

Warning: imagesx() expects parameter 1 to be resource, boolean given in /home/content/07/10456907/html/wp-content/plugins/exzo/exzo.php on line 629

Warning: imagesy() expects parameter 1 to be resource, boolean given in /home/content/07/10456907/html/wp-content/plugins/exzo/exzo.php on line 630

I’ve not used this plug in before and am not sure how much customization it needs. Any help would be appreciated.
