Hi
I wonder if anyone can help me?
I copied a picture gallery script off of the following website:
The problem i am having is that the gallery starts off fine, i can view the pics and it gives me nav links to navigate the pictures, BUT as soon as i click on the next link OR i click on a picture to view the larger version - it gives me an error message.
you can view my picture gallery at :
to get an idea of what messages i recieve.
i will also include all the code i have included in the file at the bottom of this message.
I am new at PHP so i am probably not picking a mistake up somewhere????
Please help!! i have been racking my brain.
thanks.
