Prevent Large Thumbnails From Generating in Gallery?

[AA15]

I noticed Invision Gallery is generating two files - small and large thumbnails - and it displays large thumbnails in the gallery, not the original image. This leads to higher storage since the original image is still kept on the server. Is there any way to prevent large thumbnails from generating and instead Invision just using the original image?

No, there is not.
