Content substitution, add something to page, have the last in line bumped to next pg?
I am working on a site to display pictures. I have it set up in html/css to display 10 per page, and right now i have placeholder images. I want to be able to add a new image to the top of the homepage, bumping the rest down one, and making "image 10" on the homepage "image 1" on page 2. I have created a styled template for a "page 2," but I was wondering how I might edit or add something to my site so that I don't have to continually cut/paste the image source paths "down one" from the div above to make room for a new pic at the top, and how to make image 10 on my homepage be fed to page 2.
Not looking for tons of detail, even a conceptual answer would be appreciated, something to point me in the right direction.
