change the state of a picture
Dec 17, 2013
I am using pictures as buttons. Example : you click once on a picture A and you go to the slide 2. You click once on a picture B and you go to the slide 3 ...
I would like to change the state of the pictures which have been clicked from 'normal' to 'viewed'. It would be nice for readers to see which topics have been visited and which not yet.
Would you be so kind to explain me how to do that ? Nothing is happening when using triggers 'change state of'.
