    Hello,

    Thank you for contacting us.

    In order to add image to a worksheet, my suggestion is to use topLeftCornerCell and bottomRightCornerCell along with WorksheetImage.

    I have modified your sample, let me know if I am missing something.

    Code snippet:

    // Add image
    var image = "data:image/png;base64,iVBORw0KGgoAAAA....";


    var imageShape = new $.ig.excel.WorksheetImage(image);
    imageShape.topLeftCornerCell(sheet.getCell('C9'));
    imageShape.bottomRightCornerCell(sheet.getCell('F10'));
    sheet.shapes().add(imageShape);

    It is recommended to use base 64 encoded image, currently you cannot pass an IMG element to create a WorksheetImage. If you want to use Image my suggestion is to draw that image into a canvas and then use the toDataUrl to have it create a data url that you could then use when creating a WorksheetImage.

    Let me know if I can be of further assistance.
