Ask your friends for a picture if they take it…

+Fifteen years ago, Facebook was amazing for this: everyone posted all the pictures they took at [event] and tagged everyone who was in them. But, you know... That wasn't as profitable as all the [everything else] they thought up, and they ruined the platform.

Practical suggestion: you can ask. Someone takes a picture with you in it, say "hey, you mind sending me that?" Like lots of social things it's not automatic (which, you know, Facebook was for a few years, and that was nice), and you have to "put yourself out there" a bit. Most people won't say 'no', and the thread with the photo is an opportunity for further interaction, if you want it to be.

“Hey send me that one.”

or

“Hey let’s get a selfie.” (Do young people not say this anymore?)
