hey jessica,
yes, there is a setting for that. please check in your easyblog backend at templates -> then click on the template you're using.
in the now opening new page you should see lots of settings related to your design, at the left side there's a box called "Image Display Settings" with two options.

"Show blog image on frontpage view" - if set to yes the blog image will appear on the frontpage and "Show blog image on entry view" - when you set this to yes as well it should bring up your pic in the post itself.
hope that helps
