Embed Snip Tool image in InDesign

Here is a copy of the first script from 2010 if that helps:

//DESCRIPTION: "Unpaste" pasted images
// Peter Kahrel -- www.kahrel.plus.com
// Pasted images (i.e. images without a link in the Links panel)
// are written on disk in a subdirectory of the current document's folder.
// The subdir is called "/images".
// Images can be linked or deleted
#target indesign;
