how to get necessary pngs from html/iframe?

[emezir]

Hi, background and puzzle piece pngs are supposed to be located in:

<canvas class="geetest_canvas_bg geetest_absolute" height="160" width="260"></canvas>
<canvas class="geetest_canvas_slice geetest_absolute" width="260" height="160"></canvas>

but is there a straight forward way to save them? i'm not using selenium, and cannot but from a chrome web app

Those canvas can be found anywhere, try to look in the source page code for that class names and you'll get the specific full path.
