we would like to use different key project images in the portfolio overview, depending on search categories. for example: projects (fashion style 1,2,3,...) includes images A (hat), B (shirt), C (trouser) and D (shoes) with image B defined as key project image. when projects are sorted by categories, we would like to see the rearranged project key images changing depending on the category chosen. when category "trousers" is chosen, the key project images of all projects should switch to C (trouser) in the overview portfolio page. is this possible?
