I am currently learning Wordpress development, building out a portfolio theme.
I would like advice on what's the best way(noob question), development wise, to dynamically display featured images on the front-page.
Currently, I have 5 images that are hard-coded and styled in a grid, each displaying a title on hover.
I don't want to add the images as individual posts per se, since they are not really posts and only to be featured on the front-page. The images should however be linked to a project page that lists the images all with additional info.
Is it overkill to create a custom post type for just 5 featured images that are part of a project and that will just link to a template page called project?
