Script to anchor all images in document to the closest paragraph.

Hello,

I've asked this question in the general forum and they said that I should ask here.

I need to export a document to ePub, and this document has at least 200 images.

I know that I have to anchor them to the text because if not they will all be at the end of the ePub.

I've found a script in a post 6 years ago that seems to be almost what I want.

main();  
function main()  
{  
  var doc = app.activeDocument;  
    
 var count=0;  
   
 // loop through all pages  
 for(i=0; i<doc.pages.length;i++)  
 {  
        var page = doc.pages.item(i);  
           
        if( page.textFrames.length<1) continue;  
  
        var textFrame = page.textFrames.item(0);  
  
        if(page.rectangles.length<1) continue;  
  
        // loop through all rectangles in the page  
        for(j=0;j<page.rectangles.length;j++)  
        {  
                var imageRect=page.rectangles;  
                                  
                if(imageRect.images.length<1) continue;  
  
                var myAnchoredFrame=anchorImage(doc, textFrame, imageRect);  
                var pos=[imageRect.geometricBounds[1],imageRect.geometricBounds[0]]  
                imageRect.remove();  
                j--;  
                textFrame.recompose();  
    
                var k=0;  
                  
                // Reposition the anchored image. This is done repeatedly because the first call not moves the  frame to the correct position  
                do  
                {  
                    myAnchoredFrame.move(pos);  
                    k++;  
                 }  
                while(k !=5);  
              
               count++;  
        }  
}  
  
alert("Fixed "+count+" images");  
}  
  
function anchorImage(doc, textFrame, imageRect)  
{  
        var myAnchoredFrame=CreateAnchor (doc, textFrame);  
  
        var imBounds = imageRect.geometricBounds;  
        var frBounds=textFrame.geometricBounds  
  
        myAnchoredFrame.geometricBounds =  [imBounds[0]-frBounds[0], imBounds[1]-frBounds[1],   
                          imBounds[2]-frBounds[0], imBounds[3]-frBounds[1]];  
  
        // Copy image into the anchored frame. Didn't find a better way  
        var imagePath=imageRect.images[0].itemLink.filePath;  
        var image=imageRect.images[0];  
        var filePath="D:\\im";  
        image.exportFile(image.imageTypeName,filePath);  
        myAnchoredFrame.place(File(filePath));  
          
        // Resize image  
        var newImBoundX=myAnchoredFrame.geometricBounds[1]-( imageRect.geometricBounds[1]-image.geometricBounds[1]);  
        var newImBoundY=myAnchoredFrame.geometricBounds[0]-( imageRect.geometricBounds[0]-image.geometricBounds[0]);  
        var newImBoundX1=newImBoundX+( image.geometricBounds[3]-image.geometricBounds[1]);  
        var newImBoundY1=newImBoundY+( image.geometricBounds[2]-image.geometricBounds[0]);  
          
        myAnchoredFrame.images[0].geometricBounds=[newImBoundY,newImBoundX,newImBoundY1,newImBoundX1];  
          
        //Set textWrapPreferences of the images  
        myAnchoredFrame.textWrapPreferences.textWrapMode=imageRect.textWrapPreferences.textWrapMode;  
        myAnchoredFrame.textWrapPreferences.textWrapOffset =imageRect.textWrapPreferences.textWrapOffset ;        
       
        return myAnchoredFrame;  
 }  
  
function CreateAnchor( doc, textFrame)  
{  
  
        var inPoint=textFrame.insertionPoints[0];  
        var anchProps = doc.anchoredObjectDefaults.properties;  
        var anchCont = anchProps.anchorContent;  
  
        var myAO = inPoint.rectangles.add();  
  
        // Make new object with correct default settings  
        // Make new object right kind of object  
        myAO.contentType =ContentType.graphicType;  
        // Recompose parent story so geometricBounds make sense  
        inPoint.parentStory.recompose();  
        //save users measurement preferences  
        userHoriz = doc.viewPreferences.horizontalMeasurementUnits;  
        userVert = doc.viewPreferences.verticalMeasurementUnits;  
        doc.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.points;  
        doc.viewPreferences.verticalMeasurementUnits = MeasurementUnits.points;  
  
        doc.viewPreferences.horizontalMeasurementUnits = userHoriz;  
        doc.viewPreferences.verticalMeasurementUnits = userVert;  
        myAO.applyObjectStyle(anchProps.anchoredObjectStyle);  
          
        if (anchProps.anchorContent == ContentType.textType) {  
            try { // might be null  
            myAO.parentStory.appliedParagraphStyle = anchProps.anchoredParagraphStyle;  
            } catch (e) {}  
        }  
      
        myAO.anchoredObjectSettings.properties = doc.anchoredObjectSettings.properties;  
        myAO.anchoredObjectSettings.anchoredPosition=AnchorPosition.anchored;  
        return myAO  
   }  

But this script is giving me the error "The specified object does not support the desired export format".

Any ideas how to fix this?
