Image Reveal w/Quiz

It really depends on the type of questions you're using and what you mean by ‘generate image.’ One approach is to simulate this using a Pick One Freeform question. Each response can trigger a state change on an image, allowing you to animate it in a way that mimics an image being generated or loaded.

You could also enhance this effect by using JavaScript in the background to create a more realistic ‘loading’ animation, instead of relying on the default top-to-bottom wipe animation in Storyline.

If you're just starting out, I’d recommend experimenting with different question types and seeing which one best fits the interaction you're trying to achieve.

I don’t have a ready-made template or interaction for this, but the idea below is just a starting point. I’d suggest first defining your concept, maybe sketching a simple layout or mockup of how you want it to look. Having a clear idea in place will make it much easier before moving on to the more technical work in Storyline.
