Template still offsetting

okay for the most part, my blog is fine except for the additional pages i’ve added for (About Us, Contact, Affiliates, and Shop). For some reason, if i post a picture before the article on these pages, it causes the photo to overlap outside of the text box such as…..

^ as an example. It’s going to do this everytime i post a picture in one of these seperate pages, but i want it to post like it does on the main blog. Can anyone help me fix this problem? I’d really like to be able to add some photos before adding info on those pages. I dont necessarily know where it is in my script to fix this issue, hope someone can help point it out for me and walk me through it. THANKS IN ADVANCE!
