Creating Image Gallery by notepad - problem

Unfortunately im haveing a little problem with what is a great tutorial ( thanks notepad !).

I read the whole thing, but have ended up just copying and pasting the whole thing because I am haveing problems. I have read the other threads on the same subject, but don't seem to be relivent to my self.

I am getting the error:
Notice: unserialize(): Error at offset 0 of 4 bytes in C:serverwebsites2004images.php on line 84

it seems to be the same error once for each image.

I have defined PATH to be: /server/websites/2004/renders/
and is located at c:serverwebsites2004renders

I am hosting the scripts my self on my dsl connection (I do all my testing etc my self) on a winXP pro box, with IIS and the latest version of php, I have GD2 working as I tryed a simple drawing script on it.

my phpinfo() is currently at http://81.86.255.165/2004/test.php

I think maybe my server path is definded wrong.

Im greatful for any help, I have learned allot from this tutoral and really want to get what could be a very useful and customisable script working !

You should beable to see the script running at http://81.86.255.165/2004/images.php

the urls should work unless I have to re-connect my dsl, since the ip is not static

Thanks in advance

a notice isn't anything to worry about, if that's the only problem just place an @ symbol at the beginning of the line causing it.
