Update – this is the code for index.php which is giving me the fatal error, it’s as copied from the screen cast

this is the code from the imgbrowz0r.php – more or less out of the box from download.

i’m using a a folder nameed test obviously and as per the screencast 64 have set up folders, cache, css, images, gallery, inc, js, the imgbrowz0r php file is located in "inc" and I have loaded 4 random images of my desk top into the "gallery".
The fatal error is in line $gallery->init();
which I understand loads an object? The only thing I can summise is the the imgbrowz0r php code is different in Chris version to that I’ve downloaded – I can’t for example see any random function in this version!
Thanks for looking.
