why so many cookies

[afterburn]

hello please help

I've installed the latest version of this software .. it's really cool.
I've stopped users from registering as I'm the only one who needs to upload photos.
Everything is working fine ...

However when I browse my site I get two cookies the cpg143_data I can understand, the second one at the bottom I don't understand.
I only get it when I load a page from my image gallery!  Does any one know what it is and do I need it.  Can I stop it?
Cheers Matt

The second one is the authentication cookie. You need that unless you are bridged.
