Hi,
I have an archive page which shows groups. They have a post category of group and a tag which relates to the type of group, e.g. health & fitness, social, children etc. This page allows groups can be filtered by tag to show only groups with that tag. I want my header image for this article page to dynamically change depending on the tag which is selected. I think I need to set up 5 images, one for each tag, and have conditional logic for each one to say ‘if current tag is health& fitness, show this header image’ and so on for each tag/image. But how do I actually do this?
