Why aren't my images rendered?
html2canvas does not get around content policy restrictions set by your browser. Drawing images that reside outside of the origin of the current page taint the
canvas that they are drawn upon.
canvas gets tainted, it cannot be read anymore. As such, html2canvas implements methods to check whether an image would taint the
canvas before applying it. If you have set the
allowTaint option to
false, it will not draw the image.
If you wish to load images that reside outside of your pages origin, you can use a proxy to load the images.

Why isn't SVG images getting rendered?
As with the previous question, SVG images taint the canvas with many browsers regardless of where they are hosted, or even if they are inline.
Why doesn't CSS property X render correctly or only partially?
As each CSS property needs to be manually coded to render correctly, html2canvas will never have full CSS support. The library tries to support the most commonly used CSS properties to the extent that it can. If some CSS property is missing or incomplete and you feel that it should be part of the library, create test cases for it and a new issue for it.
