img inside div does not appear when used canvas2image

I'm using a script to save a div in png. Within this div has one, but this image does not appear in the final result after saving. The code I'm using is this

$(function() { 
$("#btnSave").click(function() { 
    html2canvas($(".container-assinatura"), {
        onrendered: function(canvas) {
            theCanvas = canvas;
            document.body.appendChild(canvas);
            var photo = canvas.toDataURL('image/png');

            //Convert and download as image 
            Canvas2Image.saveAsPNG(canvas);
            // Clean up 
            document.body.removeChild(canvas);

         }

      });
   });
}); 

Remembering that this script does not work in Chrome, only in Mozilla, and here in the company where I work, for which I'm developing this, 95% of people use Chrome. Edit: The HTML of my code is this

<div style="color:#000" class="container-assinatura">
                <div id="gerador">
                        <p style="margin-bottom: 0in"></p>
