Once I have completed a page, I want to finalise it, so more alterations (accidental or deliberate) to made to the pictures. Its also easy to transfer as well, without having to worry that the correct pictures have been packaged.
Thanks for the assistance.

Well, the way to get what you want is by exporting a PDF. If it's still an InDesign file, then no matter what:
you will still need the linked image files,
you will still be able to edit objects
you will still be able to move objects around on the page
and so on. There's no way to prevent alterations in an InDesign file, that I know of. Now, if you were to give us reasons why you want this ability to finalize a given page, then we might be able to suggest the ways we'd emulate this InDesign, which are all very, very different from what you'd expect in Photoshop. However, the idea of finishing one page of a doc, and then locking it down and moving to the next page in the same document, strikes me as very odd, and not part of any sane print workflow. If you tell us why ("I want to be able to give INDDs to my coworkers where they can add text but not move or replace images"; "I want to not accidentally mess up my own work once I've marked it off my to-do list"; "I want to distribute templates from which people cannot copy objects or text") then I'm sure we can make useful suggestions; there's a heckuva lot of expertise hanging around in these forums, and someone will be able to make a reasonable suggestion.
