Sessions broken in PHP 5

Re: Sessions broken in PHP 5

Putting ini_set('sessio n.use_cookies', false); to image script solved the
problem. Thanks to arborint from DevNetwork.com for solving the problem.

I wonder why I should put it to image script. Isn't putting it to only the
main script enough? It is strange that the old code worked perfectly fine
without that line in PHP 4, but didn't work in PHP 5.
