The Problem

Manually searching through folders is slow and tiring. You might miss some pictures or open the wrong folder. It's easy to get confused and waste time.

The Solution

Listing local images with a simple command shows all your pictures in one list instantly. You don't have to search folders or remember where you saved them.
