Ftal error trying to install

Hi, I tried installing this plugin but got the following fatal error:

Fatal error: Cannot redeclare bw_gallery() (previously declared in D:\Business\Xampp\htdocs\wp-content\plugins\photo-gallery\photo-gallery.php:62) in D:\Business\Xampp\htdocs\wp-content\plugins\oik\bobbfunc.inc on line 779

Obviously a plugin conflict but I don’t want to remove photo-gallery and would like to get both these plugins working together if possible. Thanks.
