for your effort for searching, choosing the pics and creating this test.
But you know that most users are limited in viewing pictures, and most will spend them on other stuff.
These tests are usually done in a few minutes by clicking, and the answer can be seen. Your Tests are complicated to open and you have to write the answers down. If you have java script on, you can see how many users have seen a pic.
I would say that you do a lot of work for very few people.
