The photo of the dead 3-year-old Syrian boy on a Turkish beach is haunting.
It captures everything we don't want to see when we tap our phones or open our newspapers: a vicious civil war, a surge of refugees, the death of an innocent.
Largely because of social media, the image of little Aylan Kurdi is hammering home the Syrian migrant crisis to the world. Aylan died along with his 5-year-old brother and their mother when their small rubber boat capsized as it headed for Greece.
"It is a very painful picture to view," said Peter Bouckaert, who as director of emergencies at Human Rights Watch has witnessed his fair share of painful scenes. "It had me in tears when it first showed up on my mobile phone. I had to think hard whether to share this."
But share, he did. Bouckaert, who is in Hungary watching the crisis unfold, said people need to be pushed to look at the "ghastly spectacle" so they can, in turn, prod governments to help the suffering Syrian people.
Still, will the disturbing image galvanize people into action? Will it be like other seared-in-our-memory photographs — a vulture hovering over starving child in Sudan, a girl fleeing a napalm attack in Vietnam, the child in a firefighter's arms after the Oklahoma City bombing?
Or will it become just another of the many images on social media, lost amid the flotsam?
"One of the things about this story is that it's really difficult sometimes for the world to get a handle on it," said Al Tompkins, a senior faculty member at the Poynter Institute, a center for media studies in St. Petersburg, Florida. "Regardless of the technology, a singular iconic image can still touch us in ways."
And that singular image is often of a child. That was the cold fact that unsettled people around the globe.
Kathleen Fetters-Iossi, a 47-year-old fiction writer from West Bend, Wisconsin, said she hopes people share the images to create awareness, then go beyond that to try to help in some way. But she has her doubts any concrete action will come of it.
"Most Americans, if they're just now becoming aware of this issue, will ultimately feel there's nothing we can do," she said. "They feel like we can't handle our own immigration problem, let alone Europe's. Social media can help by creating wider awareness, but ultimately, 'clicktivism' didn't help the Nigerian girls, and it's not going to help those migrants."
In Greece, Alicia Stallings, a mother of two, said she won't link to the photo. It's too close to home.
"I watch my kids swim and play in the Aegean and am sometimes struck by horror when I think this is the same water in which children just like them are drowning every day," she wrote in an email.
"One hates for something like this be the galvanizing element — we are pretty hard-hearted if we can ignore all the other hundreds of drownings happening all the time. But the scale is vast, and as humans it is easier for us to comprehend one specific tragedy, in a shirt and shoes like our own kids."
The photo of the body washed up on the sand was splashed on the front of all major newspapers in Brazil, a nation with more homicides than any other, according to the United Nations. Still, the picture ignited despair and indignation.
Ary Cordovil, a 35-year-old barber, lives near one of Rio de Janeiro's slums, where a drug gang war has meant nobody leaves home after dark and schools have been shut for weeks.
"I'm used to violence. Brazil is used to seeing violence. But this — this is just painful," he said, staring hard at the image in a newspaper. "He's just a baby trying to flee a war. The absurdity of this is extreme even for us."
It inspired people like a 52-year-old grandmother from Australia to tweet multiple versions of the story.
"If these images of a dead child don't change our attitude to refugees, what will?" tweeted Jenny Fawcett of Warrnambool, Australia. Her daughter started a petition calling on the Australian government to help more Syrian refugees.
Jeremy Barnicle, chief development officer of the humanitarian group Mercy Corps in Portland, Oregon, said it remains to be seen whether the outpouring of grief on social media for Aylan will translate into tangible help.
"For many Americans, the conflict in the Middle East is distant and complicated, and therefore tough to engage on," he said. "A photo like this reminds people why we should all care."
While the image of the body on the sand was on many international websites, many U.S. sites ran a photo of a Turkish police officer carrying the limp boy in his arms. The boy's face is obscured.
Mike Wilson, editor of The Dallas Morning News, decided to run the tamer photo. He received an email from a reader who said the picture was "gory."
"I wrote back and told her that I appreciated her sensitivity," he said. "We chose it specifically because it wasn't gory. It's just a forlorn, heartbreaking image that tells the reality of what's happening."
