I also had troubles with mine and I think I finally got it down.Just updated my character sheet with an image I resized with a better website. I downloaded the image, under the 4th section (resize your image) I unselected "Keep aspect ratio" and put in the dimensions 400 x 150, I selected black for the background color. You will have to download and re-upload somewhere your image to get a permanent weblink for it.
