Random block install errors

I'm trying to us Random Block for the first time and I'm running int some errors that I can't fix after hours of searching the forum. I'm running Gallery v1.5-cvs-b291 and making a call to the block-random.php that came with the gallery install.

I get the follwoing errors:

Warning: Cannot modify header information - headers already sent by (output started at /home/virtual/site228/fst/var/www/html/gallery/test.php:8) in /home/virtual/site228/fst/var/www/html/gallery/lib/lang.php on line 349

Fatal error: Call to a member function on a non-object in /home/virtual/site228/fst/var/www/html/gallery/classes/Album.php on line 2025

Any suggestions on how to fix?

Thanks
