[Plugin: Automatic Featured Image Posts] Featured images

I need assistance with Featured Images. I would like to know how to upload an image on my post along with the beginning of the paragraph so that the picture and frist sentence show on the home page. Thus, someone needs to click on the picture or sentence to go to the full post.
The way I have it now is Post is on home page and clicking on post takes reader to complete post and picture. I need to do it both ways for my home page.
Whoever helps me figure it out wins homemade chocolate chip cookies!
