how to figure anchoring in indesign javscript

Hi rajas15536079,

You can use this line to anchor you image rectangle to specific insertion point like this:

currentImageRectangle.anchoredObjectSettings.insertAnchoredObject(currentTextFrame.insertionPoints[0], AnchorPosition.ABOVE_LINE);
// Or
currentImageRectangle.anchoredObjectSettings.insertAnchoredObject(currentTextFrame.insertionPoints[0], AnchorPosition.ANCHORED);
// Or
currentImageRectangle.anchoredObjectSettings.insertAnchoredObject(currentTextFrame.insertionPoints[0], AnchorPosition.INLINE_POSITION);

Best
