It totally depends what kind of picture it is.
If someone takes a picture of me while I'm doing something, or even pretending to do something, it's fine. Like, I don't mind pretending to shove a huge piece of food in my mouth. But if it's anything where I have to pose or I'm looking at the camera, I hate it. I get all nervous and then I look stupid in the picture.
The only thing worse than posed pictures... Photos for like, ID cards and licenses and stuff. I simply dread picture day at school every year because I know the picture is going to be absolutely horrifying, and then I have to look at the bad picture on my ID card all the time for a whole year.
The photo on my driver's permit is also pretty atrocious... But I don't have to look at that all the time, at least.
