My b2evolution Version: Not Entered

Hello all! I am brand new to these forums. I didn't want to have to ask for help with my matter but I searched through all of the plugins on these forums and also settings in my b2evoltuion control panel and I couldn't find the information that would help me. Maybe I skipped over it or maybe it's not implemented yet. Here is what I am trying to do..

here is the link to a future photo gallery on our website. there is only one post at the moment.
http://www.nonstophunting.net/photos

Basically when you click on a category on the right side, it will show all posts under that category. This is obvious. However it is not obvious to me how to make all content for each post be shown when you are in a category.

For instance go to the category "Black Bear"

There is only one post in that category at the moment but I would like for the picture to also be displayed instead of just the title and text.

I hope this makes sense. I hope someone is able to help me with this. Thanks in advance!
