I want to be able to have a read more link displayed if a blog post is a certain length, i.e. a certain number of words. At the moment all blog posts are displayed on the home page in full, unless I enter an excerpt for the post, in which case I get a read more link. The only issue with that is that any main image for the post disappears if you post an excerpt and you end up with just the text excerpt displayed. I can add a featured image manually to the post but instead of a full image I get one inside a circle above the post, which I don't want.
