Slide Show Failure (shows thumbnails)

We had to upgrade our theme because of the Google mobile update. All changes were made on a fresh install of wordpress and then made live once we knew everything was working correctly.

In the process our slide shows stopped working correctly… This is the short code

[gallery link="none" size="large" type="slideshow" ids="8458,8459,8460,8461,8462" orderby="rand"]

Two examples:
http://www.garageflooringllc.com/rust-bullet-concrete/ (Case Studies Tab)

http://www.garageflooringllc.com/ribbed-flow-through-tile/ (Pictures Tab)

The first image appears live and the rest show up as a thumbnail. In some cases there was missing database and image information. Our developer restored that manually. In these two examples and many others

I don’t know what to do with them. They have database info. I deleted all the images in one yesterday and rebuilt it from scratch…big images still showed as thumbnails in that slide show.
