Where are these 14 GB images that are occupying my Android storage?

I have been running out of storage on my android phone, the one plus 5T. I have Google photos backing up to the web and have deleted the local images post backup. Google photos and even gallery are barely taking up a gigabyte. But there under storage it does show 14 GB of images but I cannot seem to identify where these are or which app they belong to. I looked up all the usual culprits in the app list but none of them shows a claim to 14 GB of memory. Any thoughts how I can find these images and reclaim the space?
