Hide Introtext on blog post detailpage | show introtext and preview image incl. "read more" on recent blog post module

It would be very helpful to hide the intro text using the read more button in the editor on the blog post detail page. The intro text is only useful on the overview page. The intro text would be useful in the "popular blog posts" module to pique readers' interest. Furthermore, the "popular blog posts" module should display the post preview images, including the "read more" button.
