I have a webcam that uploads a image every 15 min to a folder on my webserver.
And then i have a wordpress page that display this image.

The problem is the browser caches the image and it will not update when i refresh the page after 15 min.

I have tryed different options like function wp_get_nocache_headers(), img.decoding = “async”;, and some META no-cashe stuff, but nothing works.

There is a 99% chance im doing it wrong!

Can anyone giv my a step, by step guide how to prevent browser cache on my webcam image?
And only the one page with the image.
