Well, ChatGPT is now pretty good is you can formulate a reasonable prompt. Maybe something like (not tried):
"Using HTML, VueJS, CSS and JavaScript, write a simple web page that contains 3 images but only shows one at a time based on a VueJS data variable."
Then you should be able to slot that into a ui template node. You might even be able to ask a follow-up question and get ChatGPT to do the Node-RED flow for you as well.
It doesn't always get everything right so you might have to mess around a bit but you could probably look things up more normally once you have the basic framework.
