"No Image" appearing on new images uploaded to product pages

[CharlesCarter]

Hi, 

We are experiencing an error with new images we upload. We could upload images fine Monday but today, new images are not appearing on the product page? They appear fine on collection pages but not on the individual product page. It only shows the "No Image" error.

Here is a link to our store with the specific product we are having issues with;

This occurs on the third and fourth images. 

Any help would be appreciated
