I have two questions on how to display pictures within Inquisit.First I'd like to display one of two pictures according to a prior radio button selection on a survey page.I tried to use the "/ ontrialbegin = [if(radiobuttons.coinflip.response == "abc") ..." but I didn't know how to complete this command. Or do I rather have to specify the selectionmode when defining the picture element? Do you have any advice?
