The solution is very simple, too…
As I answered previously, create the text frames and image frames you need on a parent page. Lock them. If you have unchecked the “Prevent selection of locked objects” option, only the position will be locked, but it will not prevent you to edit the content of these frames.
Of course, like any object located on a parent page, you will have to release them first to be able to select them on the current page, but it's very easy to do: select all the pages you want to work on > right click > release all parent pages objects (or something similar, that's the translation of the french menu). The shortcut is Shift Alt Commmand L on a Mac, Shift Alt Control L on Windows.
If you don't want to use parent pages you could also create a library or a snippet with rhese elements and place them each time you need them, but I thing that it will take more time.
