I am trying to add an image into a new question that have been selected as an answer in the previous question.

To do that I tried without success: {Q001.shown} - this one just shows the pathway, but not exactly the image

I also thought about trying the function if, but that did not work as well

{if(Q001=="A1",< img src="/upload/surveys/surveyID/images/image_name.jpg" >," ")}

Does anyone know what I should do?

Hi,
it is nearly correct.
You forgot the quotes

{if(Q001=='A1','< img src="/upload/surveys/surveyID/images/image_name.jpg" >','')}

And remember: No nested quotes. You see the double quotes inside the single quotes.
Of course you have to extend the function if there are other options selected in Q001.

On the other hand you could create as many questions as there are images, display with plain "<img src=.../>" and display the questions by relevance equation.
