How to Add Image Here? [Elegant Themes - InStyle Theme]

I've sent a message to Elegant Themes' staff about this issue, but I have yet to get a response, so I thought I'd give it a whirl and post here as well.

The gentleman that owns this website www(dot)buyhomesindetroit(dot)com has images and a video embedded in his page.

Where in the Theme Editor do you go to add images or text to this area? This screenshot tinypic(dot)com/r/2d9z5kx shows the data he has in the middle of his screen that I'm referring to.

I figured that I could do this by using the Drag and Drop Builder that I just bought, but I'm not able to modify my homescreen (at www(dot)detroitrealestatenow(dot)com) via any of the Page Editors, and from what I've read, the Drag and Drop Builder can only be used from within one of the Page or Post editor screens.

Do I have to include data from a page or post into the Featured Slider section of the General Settings in the Theme Editor, perhaps? If so, something's not working right, because I have data in a page entitled "Main Page", and I have "Main Page" selected for being a part of the slider (as you can see here: tinypic(dot)com/r/2d9z5kx/6 and that data isn't showing up on the homescreen.

Here's a screenshot (tinypic(dot)com/r/akv3ub/6) that shows that the "Main Page" page indeed has data in it.

I tried setting the Featured slider to use a post, I then made sure the post had an image in it. The image that was in the post isn't showing up on my homescreen.

If someone can PLEASE help me figure out how to put images and content in the middle portion of my homescreen, it would be appreciated. It doesn't seem like it should be this difficult to do.

I'm convinced that the content for that middle portion of the screen is edited using the Featured Slider somehow.

When I disable the Featured Slider, the three little boxes at the bottom of the screen moved-up (screenshot: tinypic(dot)com/r/359a2k2/6 ).

And when I enabled the Featured Slider again, they moved back down to their original spot (screenshot: tinypic(dot)com/r/345et6p/6 ).

I just can't seem to figure out how to this html code and images placed inside of that Featured Slider that I need.

I feel I've been fairly thorough in trying to get this to work, and I know you guys on this forum appreciate that.

Thanks in advance for your time.
