How to delete Images on Android 8.1.0? Android is complaining of dwindling storage space. I regularly delete personal files to comply with its demands and can now use but 20 Gb of a 32 Gb storage unit. Recently I noticed an item called Images in the Storage -> Photos &amp; videos dialogue:



The trash bin of the Photos application is empty, and so far I could not identify these "images" in the system. How can I delete them?

Update: I have wiped the system cache, follow the procedure described here. This had no effect, the phone still reports 3 GB of images that are nowhere to be found.
These are the caches Images which Android stores it in itself. To delete these Images, go to your File browser and allow the File browser to show Hidden Files and then Go to 

Phone Storage > DCIM > .thumbnails

There are image more than 100 image and some waste files stored under this folder. Delete whole folder. Doing this can help you in some Manner to get out of dwindling storage.
