@spaceshipone The use of those kind of access checks (pictures, crazy-looking text, or certain mouse movements) is a website thing that Opera or an extension have no control over. The tests are either written into the website's code or are part of a call to some remote code to perform the test. The most Opera or an extension could do would be to somehow block the testing code, but that would necessarily cause the test to 'fail' and you still couldn't access the site. Your best bet is to complain to the website(s) directly and request they change things there.
