Optimised contact sheet document from linked images

Hello community,

I've seen many posts and scripts that can create a contact sheet from files but non from linked images already in an InDesign document.

I'm looking for something that should do the following:

• take all the linked images present in a .indd document
• create a new document based on a user input size
• paste the link images with the same size and cropping of the original document and add captions
• rearrange images and captions (move and rotate) to optimise the layout for later cutting of each image

if someone could direct me to some script I would really be pleased. Otherwise if some expert have ideas on how to implement a script like this I would be happy to hear from you.

Thank you all.
