Alignment and image enlargement in Indesign

Hi Team,

I need an URGENT help to do the following:

I have an InDesign file containing 100+ pages with image on every page.
I want to center align image of a page to “Align to Page” and then enlarge the image to 126%
This needs to be repeated till the end of the document.

Can some one help me URGENTLY.

Many thanks in advance.
