The generic "fetch property values" that I wrote is capable of replacing #property in a more intelligent manner - documented at:

https://en.wikipedia.org/wiki/Module:Wikidata

For simple cases though, #property will work - for example if you paste the following into any section of an article and *preview* it, it will return the image from Wikidata:

{{#if: {{#property:p18}} | [[File:{{#property:p18}}|thumb]] |}}

Similarly, in an infobox, just using |image = {{#property:p18}} will work fine.

However, Wikidata can store multiple image filenames, so the question is: how do you want to deal with those cases?

Building a Lua call to return an image or something like Noimage.svg is a trivial job : I've made a demo module at:

https://en.wikipedia.org/wiki/Module:Sandbox/RexxS/Images

If you paste {{#invoke:Sandbox/RexxS/Images|getImage}} into https://en.wikipedia.org/wiki/Franz_Kafka and preview it you'll see "Kafka portrait.jpg"

If you paste {{#invoke:Sandbox/RexxS/Images|getImage}} into https://en.wikipedia.org/wiki/Hangthwaite and preview it you'll see "Noimage.svg"

Obviously calls can be buried inside templates to hide them from editors - either an infobox or create a template to make the image as a thumb outside of an infobox, etc.

No, but people have written templates that pull in other Wikidata
values, so it's certainly possible.

I'm blind-copying this to someone who may be able to help.
