Thanks for the great review, @leonardo67, and thanks for using SlickQuiz!
I can answer a few of your questions…
As for entering scores in the widget – the widget will automatically populate with top scores as users complete the quiz, however, you must have “Save user scores?” enabled on the SlickQuiz Default Options page for this to work.
As for images, it is possible to insert any HTML tags you like into each of the quiz values, we just don’t have the WordPress Media selector working with it. So to add an image now, you’ll need to grab the URL from the Media Library image that you’d like to add and then insert something like the following where you’d like your image to appear (replacing {THE_IMAGE_URL}
with the URL from the Library):
<img src="{THE_IMAGE_URL}" />
Lastly, as far as social invites go, it is also possible to enable sharing via the SlickQuiz Default Options page with the “Enable sharing (twitter, facebook, and email) buttons?” options. This will add share buttons to the end of quiz results, so when clicked – the social messaging will contain the user score (by default).
Hopefully that helps you out, but as always, I’d love any feedback about how the quiz could work better! Thanks again!
