Also, I have been trying ConvertPage and it's not working either, but with different results. Below is an example of what I did. It cuts off the image though and only shows about half of it.
GrabzIt("APPLICATION KEY").ConvertPage({
"target": "#paddAroundExport",
"delay": 3000,
"format": "png",
"transparent": 1,
"bheight": -1,
"height": -1,
"width": -1
}).AddTo("finalImageID");
