Don’t jump — until I get this picture lined up!

America’s selfie obsession reached a new low on Tuesday when a woman snapped a cellphone self-portrait that also captured a suicidal man on the Brooklyn Bridge.

With scores of onlookers watching the dramatic 10 a.m. rescue by cops, the crass camerawoman turned her back to the scene, angled her phone toward the bridge and snapped a shot.

The scarf-clad blonde even cracked a thin smile.

When approached by The Post afterward, she suddenly became camera-shy.

“I’d rather not,” she said when asked for her name. She then hustled out of Brooklyn Bridge Park.

The shot of the unidentified man — who was saved by officers — has instantly earned a place in the rogue’s gallery, not far behind Anthony Weiner’s infamous crotch shot and Amanda Bynes topless breakdown photos.

Selfies have become so wildly popular that the term was named word of the year for 2013 by the Oxford Dictionary.

The craze includes not just celebrities at their worst — average people have also become viral phenomena.

One of the most notorious came in The Bronx in May, when Bahsid McLean, 23, murdered his mom, Tanya Byrd, then posed with a picture of her severed head.

In October in Florida, high-school junior Malik Whiter snapped a selfie in a classroom while his teacher was seen going through labor in the background.
