No images in posts on front page of Business Feature theme


just joined and installed Business Feature theme w multi-site and BP activated. Have changed over from a magazine-style theme that used to require me to "attach" a feature image to each post to get it to display on home page as a feature image in a post exerpt – as opposed to uploading image into post body. Right? So I would have one large feature image "attached" (used a custom field/window when writing post – see screenshot) that would show on my home page but other images within the post that would show when full post was shown.

Site is:

With Business Feature none of the images I "attached" in old theme are showing as medium thumbs on Home Page, but images dropped into posts themselves are OK.

Help! I don't have to re-load all those images, do I???
