Lost Front Page Images in minutes

I was working on my site with the EZ PayPal plugin earlier today. I came back to the homepage and all images were gone. So, I went into the admin page to check the photo links. All were present as they had been previously, so I didn’t change anything. After reading the forums, I have done the following with no success:
1. Changed themes
2. Deactivated all plugins
3. Adjusted permalinks
4. Added new images previously not part of the library
5. Installed Hotfix plugin
6. Reinstalled WP 3.5

Needless to say, I am not getting anything. If you go to https://www.fitnessbyleslie.com, there should be a large slider image. You will see 3 photos beneath the open space where the slider goes, but those are installed with the theme and not my own. The sub titled “Pregnancy Fitness” should be showing an image I loaded. However, you will see that is not the case either. This is the only location I actually have photos posted, so I would think its an easy fix. I am new to this, so I dont understand all coding lingo. Can someone help me get the images back? Thanks.
