Media & Geolocation
Reverse image search (Yandex, Google Lens, TinEye) finds where a photo already appears online, exposing reused, stock, or AI-generated images. It is a core media-verification and fact-checking technique for confirming whether an image is authentic and original to the story it claims to illustrate.
A reverse image search takes a picture instead of words and asks the engine where else that picture lives. Yandex, Google Lens, and TinEye each index the web differently, so a verifier runs a photo through all three to widen coverage.
The payoff is provenance. If a photo billed as breaking news already appears in a years-old article, a stock library, or another country's feed, it is recycled and the claim is false. AI-generated and stock images surface the same way.
This is verification, not surveillance: the goal is to authenticate the image and trace its first publication, the same workflow fact-checkers and newsroom verification desks use to vet user-submitted photos.
Run a photo through Yandex, Google Lens, and TinEye.
Earliest match usually points to the true source.
Stock or older matches expose reused or AI images.

# Google Lens / Yandex / TinEyeA reverse search surfaces every page where a photo already appears, letting you trace it back to its earliest known publication.
# find where an image appears onlineMatches against stock libraries or older posts expose a photo as recycled, staged, or AI-generated rather than original to the claim.
# detect reused or stock or AI imagesConfirming where a profile picture truly came from is a media-verification check — for example, flagging a stock headshot reused on a fake account.

Type the implementation, repair mistakes and work through every recall exercise.
Use the final check without hints; revisit weak concepts in short practice sessions.
