You are linking to the page instead of the image, copy the image url instead..
Issue is, after event 2 has run, event three will allways run, because it's conditions are immediately true that tick.
So one way to solve this would be putting the animationframe check as a subevent and using an else statement.
Another would be having a boolean variable on sprite6 and toggle it on left click, after which you could check the boolean and set the animation-frame accordingly..
