Running a multi-store, the images are working except on the main store.

[AUSMayhem]

Running into an issue with the product images on the default (main) store, as all the product images on the category page does not load correctly as the place holder images gets loaded instead. 

On product pages, all the thumbnails loads the correct image, however big main gallery image does not load and is replaced by the place holder image.

Some of the products on my main store are on the second store, and all the images loads correctly on the second store, and not on the first store. 

I've ran php bin/magento catalog:images:resize and it hasn't resolved my issue.

The way I got the data into the system, was using the data migration tool. 

Any insight into this would be grateful.

Worked it out, for those interested and for future users. Using the data migration tool, the water mark image was imported into v2, the water mark image was smaller than the actual image dimensions, causing an exception within the code.

Solved by removing the water mark image.
