Problem: Sometimes, e.g. when you have a file in your computer but you don't know its original name, or even if it's a file from Commons, the search for it can be fatiguing, by trying to guess its title.
Proposed solution: Enable a basic search engine by image just as Google Lens, showing the thumbnails of the wanted image along with the bests matches, if it doesn't exist yet.
Who would benefit: Users who need to find the origin of their images, or have forgotten it.
