AI Image Quiz: two images, one real photo. Can you find it?
5 rounds · about 15 minutes
How it works
1
Look closely
Every round shows two images, A and B. One is a real photo, the other was made by AI.
2
Vote
A or B? Hands up, cards, or the quiz question in LessonUp.
3
Check the clues
The answer shows the real photo and what gives the AI image away, if anything does.

ROUND 1 · ANSWER
B is real
What gives A away?
1
One board, two riders
The green surfer has no legs and no board. His body ends at the red surfer's head.
2
Reflections disagree
The red rider has a bright red reflection. The blue rider's reflection has no blue at all.

ROUND 2 · ANSWER
A is real
What gives B away?
1
Two mats fused into one
The black mat runs straight into the end of the grey mat instead of passing behind it.
Hint, not proof: everyone has the same age, hair bun and stiff pose.

1
Weightless bird?
The flower sits on a thin stem, yet it does not bend at all under the bird.
Only a hint, not proof: small birds can perch on flowers.

ROUND 4 · ANSWER
B is real
What gives A away?
No visible flaw
Hands, strings and the building all hold up, even zoomed in. There is nothing you can point at.
At most a hint: a perfect smile into the camera, a postcard-clean backdrop. Real photos can look like that too.

ROUND 5 · ANSWER
A is real
What gives B away?
No visible flaw
Even zoomed in there is nothing you can prove. Odd build, though: lettuce at the bottom and in the middle, tomato under the meat.
When looking is not enough: reverse image search, find who posted it first.

Be honest: your eyes are not enough
2 of 5
AI images in this quiz had a flaw you could prove. The other three only had hints, or nothing at all.
Modern AI images can no longer be reliably recognised by eye.
The newest models get hands, text and reflections right. The flaws in this quiz come from images that are easy enough to practise on. Real fakes in your feed will often show nothing at all.
A flaw proves a fake. No flaw proves nothing.

What still helps
1
Pause first
Don't like, share or comment yet. Every reaction helps a post spread, even a doubtful one.
2
Reverse image search
Google Lens or TinEye: where else does the image appear, and since when?
3
Detectors & labels
SynthID, Content Credentials, "AI info" labels. A signal, not a verdict.
4
Check the source
Who posted it first? Do real news outlets report it?
