Where to insert image links in javascript code?

Question

I am having trouble adding images links to the questions. I'm not going to use the questions in the code. There will be 20 questions that are "What Star Wars Character is this?" so the user will have to guess the character based on the image. Where exactly would I put the image link and what other code will I have to add? Thank you very much!

Seams to me, You need to add id for each image used in quiz/set of questions and then assign answers with correct image id.

Have fun!
