Images in Services section

I just purchased and installed this theme today. I clicked on "Theme Instructions" from the Wordpress dashboard and it came up Page Cannot Be Found. So then I clicked on "Theme Instructions" beside these forum posts and found the Intuitive Pro theme is not listed. My question is about the images that are in the default setup of the Services section on the Home/Frontpage from the downloaded demo content. When I went to Customize > Theme Options > Layout Options > Services, and changed it from 3 items to 5 and selected Pages instead of Categories and selected the 5 pages, it resulted in the images that were displayed between the Service titles and excerpts disappearing and a placeholder put there instead. I can't find a place to edit those images. Can you please tell me how that is done? Thanks http://ohs.ara.bc.ca
