Rename (with suffix) and relink an selection images

[edov68852173]

Is it possible by means of a javascript to rename a selection of images of a document in a bulk with a suffix and relink. (For example: filename.jpg to filename_C.jpg)

Yes, you should familiarize yourself with the File object and Link object. Link.copyLink(File) is going to be your primary mode of doing so.  Edited with a demonstration (you'll want graphic containers (ie rectangles and/or ovals) selected): 

var sels = app.selection;
var suffix = "_C";
var extRegEx = /\.[a-zA-Z]+$/gi;
var aLink, linkName, linkExt, linkNameNoExt;
for (var i = 0; i < sels.length; i++) {
   try {
       aLink = sels[i].graphics[0].itemLink;
       linkName = aLink.filePath;
       linkExt = linkName.match(extRegEx)[0];
       linkNameNoExt = linkName.replace(extRegEx, "");
       aLink.copyLink(File(linkNameNoExt + suffix + linkExt));
   } catch(e) {}
}

Note that this creates a copy of the image in its original location, rather than renames it. But it's the easiest way to do it.

Thanks Brain311 it works!!!

And is it also possible with a selection in the 'links' panel (selection of images on different pages)?

[brianp311]

No. Those selections are not accessible. Selections only work on a single spread. If you want it to operate on images across pages, you'll need some kind of logic in the code to grab the right ones.

Ok! Thanks!

A fine to place to start is to get allGraphics of a Document object, then iterate through them. 

var ags = app.activeDocument.allGraphics;
var aLink;
for (var i = 0; i < ags.length; i++) {
    try {
        aLink = ags[i].itemLink;
        //your if (someCondition) code here
        //look at the Link object API here: 
        //https://www.indesignjs.de/extendscriptAPI/indesign-latest/#Link.html
    } catch(e) {}
}
