Theme Installation Problem

I have Hostgator as my host and installed WordPress on my newest domain with ease. I downloaded a theme called Snapshot and unzipped it. I FTP’d it correctly to wp-content/themes/ so it reads wp-content/themes/snapshot but even after I activated the theme in Admin, a lot of the images still aren’t loading on the theme whenever I load the website. I go to the Images folder on the host and all files are present.

It’s my first time using WordPress, is there something I’m missing in terms of activating the theme so the images show up?

Thanks in advance,

Andrew
