I am a complete novice so have patience with me
I am creating a photo book for a uni project. I have created one before but I had help (which was pretty much done for me with no explanation)
I have placed an image box on what will be the first of the image pages. I want to be able to sort of...copy and paste the positioning of this box onto the remaining pages.
I don;t want to have to manually create a box everytime I finish the previous page as I am concerned about whether I will be placing it in the right place
You should use master pages.
You can create a box at the top of this page, and then apply that page to all the pages you want the box on. Check out this video tutorial for more on this: http://www.youtube.com/watch?v=zZ54XNNNLWc
What you want to take advantage of is Master Pages. For example if you were going to want the current page number to appear on every page of your Book you don't have to do them one by one. You can set it up in a master page. Same thing for your object box. Just double click Master A and create your object box of the appropriate size and where you want it positioned on every single page and it will apply it. This is how you create "page templates" within your InDesign documents that you can use for different elements that need to be consistent across multiple pages in your layouts.
