Reply To: Alignment and image enlargement in Indesign

Hi Masood, this could be scripted, of course, but I’m thinking for 100 pages it would only take 10 or 15 minutes to do it manually. You can center it by cutting it to the clipboard. pressing command-zero to fit page in window, then pastting (because paste always places the object in the middle of the screen). You can adjust one image, then go to the next page and repeat using Object > Transform Again.

Or, if the object is in the same place on every page, and you just need to move it and enlarge it the same every time, then you could use Transform Sequence Again:
