Some pictures aren't showing up on CMS Masters theme.

I cannot for the life of me figure out what is causing the problems with displaying the "bio" area of City Council.

Any help you be greatly appreciated. You will see that the first two "bio's" for Mayor and Mayor Pro-Tem are coming up correctly. Then, moving on to the rest of them, it's having an error. Yet, through the dashboard, I can see the images in the content editor.

Any suggestions? Link is below.
