LinkedIn shows Image preview differently when the post is shared on a LinkedIn Profile or Page. It works based on LinkedIn API so we are not able to change preview when the post is shared. LinkedIn has its own preference to show how the post will display shared including URL or without URL in the post content.
So it depends on what type of content you are sharing and sharing on Profile and Page has a different layout to display image post.
See, how your images will look on LinkedIn when shared:
LinkedIn Profile: Image post with URL
LinkedIn Profile: Image post
LinkedIn Page: Image post with URL
LinkedIn Page: Image post
