How can I get images placed in InDesign to stay 100% scale

The thing is, I work in sort of frenzy. I want an option where I can just check everything globally at the end. I didn't do any more work on this Sunday but I'm going to try the object styles & see.

Perhaps this “report” will do what you want:

Or perhaps a tab delimited text file that you can open as a spreadsheet and sort or filter on the Scale X/Y % columns:

// LinkExport-Pro_1a.jsx 
//DESCRIPTION: Exports some information about placed images in the active Document into a textfile in the same folder as the document.  
// The values are tab-separated, so that the content of the file can be copied to Excel via Clipboard. 
// The exported textfile has the ending ".txt". 
// Script by Martin Fischer (www.hilfdirselbst.ch)
// 
var myDoc = app.documents[0]; 
if (myDoc.saved == false) 
{ 
  alert("Error.\rYou must first save your document."); 
  exit(); 
} 
var myDocName = myDoc.name.split(".indd")[0]; 
var myTXT_File = myDocName + '.txt'; 
var myPath = myDoc.filePath + "/"; 
var myCreator = "R*ch";  
var myType = "TEXT";  
var theFiles = myDoc.links; 
var myData = "link\tpath\tpage\twidth\theight\t% vertical\t% horizontal\teff. PPI\r";  
var f = new File( myPath + myTXT_File );  
f.open( 'w', myType, myCreator );  
f.writeln( myData );  
for (myCounter = 0; myCounter<theFiles.length;myCounter ++ ) {  
  var myBounds = theFiles[myCounter].parent.geometricBounds;  
  var myWidth = Math.round(myBounds[3]-myBounds[1]);  
  var myHeight = Math.round(myBounds[2]-myBounds[0]);  
  var myScaleVert = Math.round(theFiles[myCounter].parent.absoluteVerticalScale); 
  var myScaleHori = Math.round(theFiles[myCounter].parent.absoluteHorizontalScale); 
  var myImagePath = theFiles[myCounter].filePath; 
  // WARNING if vertical scale is different to horizontal scale 
  if (myScaleVert != myScaleHori) 
  { 
  var myWarning = "% vertical is not equal % horizontal"; 
  } 
  else  
  { 
  var myWarning = ""; 
  } 
  try  
  {  
  myPPI = (theFiles[myCounter].parent.effectivePpi); 
  }  
  catch (e)  
  {  
  myPPI = 0; 
  }  
  var myClass = theFiles[myCounter].parent.parent.parent.constructor.name; 
  // image placed on page 
  if (myClass == "Page")  
  {  
  myPage = theFiles[myCounter].parent.parent.parent.name; 
  }  
  // image embedded 
  else if (myClass == "Character") 
  { 
  try  
  {  
  myPage = theFiles[myCounter].parent.parent.parent.parentTextFrames[0].parent.name; 
  } 
  catch(e) 
  { 
  myPage = "versteckt im Überlauf"; 
  } 
  }  
  else { 
  try  
  {  
  // image placed outside the pages 
  myPage = "Spread of " + theFiles[myCounter].parent.parent.parent.pages[0].name; 
  }  
  catch(e)  
  {  
  // don't know the page where the image is placed 
  alert ("Class: " + myClass + "\r" + theFiles[myCounter].name); 
  }  
  }  
  myData = theFiles[myCounter].name + "\t" + myImagePath + "\t" + myPage + "\t" + myWidth + "\t" + myHeight + "\t" + myScaleVert + "\t" + myScaleHori + "\t" + myPPI + "\r"; 
  f.writeln(myData);  
}  
f.close(); 

tell application "Adobe InDesign CC 2018"
    set transform reference point of layout window 1 to center anchor
    set properties of all graphics of active document to {horizontal scale:100, vertical scale:100}
end tell

OK I don’t want to change the positioning of any of the images at all. This is b/c the images are positioned so that a specific part shows.
