Well I can't really think of one specifically, but any photos that show abuse, cruelty or make fun of people in a not nice way really upset me.
I once saw an LOLcat picture where it was A TON of kittens in hamper sack or something. It was taken to be funny, but I agreed with a lot of the comments where that's just cruel as they're all piled on top of each other and clearly they're struggling to get out - gotta feel bad for the poor kittens that got stuck on bottom with all the others on top - that's just cruel!
And of course the Urban Outfitters ad with the super skinny teen wearing the "Eat Less" shirt - something like that which promotes troublesome stuff, I'm just not a fan of.
I guess you could say photos of my ex upset me a bit too - I removed all the photos of us together during those years in college and put em all in an envelope. I'm not one to burn or destroy photos and stuff like that (unlike my sis apparently), as who knows, maybe one day I won't be so bitter towards him for wasting that much time of my life and I'm sure our kids will probably one day ask about our exes as well. As much as I hate that I wasted nearly 3 and a half years with him, hoping he'd get his shit together and we'd have a future together, there were some fun times during our first year or so, although things toward the end and even after kind of jaded my feelings towards the entire relationship. I just prefer not to keep those photos handy as at this point in my life, it just angers and upsets me to look at them, as it reminds me what a lazyass he turned out to be and the waste of time I spent with him during the majority of my college years. Maybe one day I'll be able to look back at them and remember the good times, but for now, I'd rather not.
What photos anger you or make you sad?
