Why is my screenshot blank?
The most common reason is that the given URL is a redirect
(the screenshot app doesn't follow redirects). Enter a URL
that is an actual web page.
Does Super Screenshot support Flash?
Yes, Super Screenshot loads Flash, but the screenshot is taken
the instance the page is loaded. If the Flash app starts blank, this is
how it will be shown in the screenshot.
This is not the way the page appears to me
If the URL is behind a login screen or is the result of your current session
or other cookies (like a shopping cart), the page will be shown without
this context like the first time you visited this URL.
Why does the screenshot take so long to load?
To make a screenshot, Super Screenshot downloads your URL in a browser,
renders the HTML, and the page is captured to a file. If the
web page contains a lot of images or advertisements, it can take several
seconds to load the page.
What rendering engine does Super Screenshot use?
Super Screenshot renders pages with the Safari browser.
