First thoughts

Looking through the images, it seemed like all the images had identical backgrounds. Thus I tried taking the image with the least foreground and applying stenography.

Then I tried manually guessing the flag, since surely there weren't that many...

Lmao whoops

On Cyril's suggestion, I looked through all the images again, and noticed a very obvious difference in this image

Solution

Flag: DUCTF{FLAG_ON_THE_PRIZES_TWITTER}
