i have a photo gallery that is made of two pages: one is a simple html with Thumbnails and when you press a thimbnail it opens a window with the enlargement of the thumbnail. and you can also step through the pictures in the window with buttons . so i built an array and i have functions for going forward and backwards. and in order to show the picture i have this:

  
ShowPhoto (Images[loc].src);
//Images is the name of my array
    }
        function ShowPhoto (filename)
    {
        pic.src=filename;
        pic.alt="Filename: "+filename;
        window.status=filename;
 
    }

so loc represents the number of the picture that is going to show. and what i think i need to do is to be able to change loc from the page with the thumbnails according to the thumbnail that is being pressed.
how can i do it? can any bodey help me? thank you

window.location = "your new page";

Incorporate that into a separate function for your paging buttons and away you go.

in which page do i add this? in the window or the one with the thumbnails?
and how exactly this refer to loc?

actually where is the declaration path of where should take that thumbnail.

pizza: you add it to wherever your paging links are. You'd have to create a separate function for it though, in all likelihood.
