dynamically present content based on paricitpant's choices

[Alexpathy]

Hi!

Could you help me with the code for a simple interactive task?

I want to present participants with a choice between two pictures:
Depending on which picture they choose, they will presented with text A or B.
The text that participants are presented with should be paired with a picture that is chosen randomly from a seperate list.
It is important that participants can input text while attending the paired text and picture.
The process is iterated over multiple trials.

What I got so far is pasted below. Obviously I don't have a list with pictures that are sampled (I will sample without replacement). If you include an example list I can probably work it out from there.
What I want to do is basically present my chosen picture together with what I got in my variable "trialtest" as the returned content in the variable "testfeedback".

var test = {
  type: jsPsychHtmlKeyboardResponse,
  stimulus:`
      <div style='width: 700px;'>
      <div style='float: left;'><img src='stimuli_img/DESCRIBE.jpg'></img>
      <p class='small'><strong>Press the A key for option "DESCRIBE"</strong></p></div>
      <div style='float: right;'><img src='stimuli_img/FEEL.jpg'</img>
      <p class='small'><strong>Press the K key for option "FEEL"</strong></p></div>
      `,
  choices: ['a','k'],
  on_finish: function(data){
    // Score the response as correct or incorrect.
    if(jsPsych.pluginAPI.compareKeys(data.response, "k")){
      data.correct = true;
    } else {
      data.correct = false; 
    }
  }
}

var testfeedback = {
  type: jsPsychHtmlKeyboardResponse,
  stimulus: function(){
    var last_trial_correct = jsPsych.data.get().last(1).values()[0].correct;
    if(last_trial_correct){
      return "FEEL"; // the parameter value has to be returned from the function
    } else {
      return "DESCRIBE"; // the parameter value has to be returned from the function
    }
  }
}

var trialtest = {
  type: jsPsychSurveyText,
  preamble: `<img src="stimuli/CFD-BF-037-013-A.jpg" style="width:400px;"></img>`,
  questions: [
      {prompt: 'How old are you?',
      required: true,
      rows: 5,
      columns: 30
    },
  ]
}
timeline.push(test, testfeedback,trialtest);

Someone's got any ideas?
Many thanks!
