Hi, 
I want to have a trial where two pictures are presented side by side and then participants will be asked to choose either the left one or the right one. 
The pictures being presented on the left or the right side of the screen will be counterbalanced across participants. I was able to do this. 
But I wonder if it is possible to 
(1) present the pictures first and the question will show up later, so that participants can look at the pictures first without being disturbed by the question. 

(2) record participants' responses so that I could easily know which picture they chose. (If I only know they chose the left picture or the right picture, I won't know if the left picture they saw was picture 1 or picture 2, due to the randomization of presentation side.)

Below is the code I have so far. Thank you so much!

Set up a <trial> that displays the two pictures, from there /branch to the surveypage with your question.

I don't understand this question. You should have everything you need to make that determination in the data file.

Beyond that, whenever you must share code that requires external files to run (here: a few images), provide all necessary files, please.

I don't understand this question. You should have everything you need to make that determination in the data file.

Here's a basic revision of the code:

/ stimulustimes = [0 = CandidateAtext,CandidateBtext,CandidateApicture,CandidateBpicture]
/showpagenumbers = false
/showquestionnumbers = false
/ nextlabel = "continue"
/ finishlabel = "continue"
/ branch = [
    surveypage.nonsexualcandidates_question;

</surveypage>

<surveypage nonsexualcandidates_question>

    if (radiobuttons.CandidateABchoice.response == "Candidate A") {
        values.selected_image = picture.CandidateApicture.currentitem;
    } else if (radiobuttons.CandidateABchoice.response == "Candidate B"){
        values.selected_image = picture.CandidateBpicture.currentitem;
