Some people just have no shame, flaunting their bad habits for all to see. Like coke 'n' roll super-couple Kate Moss and Pete Doherty, who recently started rival scab collections. And Nicole Richie, who went from curvy to scurvy in about two weeks, like we were going to believe any crash pilates-and-Altoids diet was going to do the job that fast. It's the drugs, man. So when I read that local rock photographer Bill Ellison was asking his subjects for a "bump" when he photographed them, I figured that was the last snort...er, straw. Turns out, I just can't read. Ellison's been asking his subjects not for quick hits of the white devil, but to "jump" when they're photographed. So it's a high of a different kind. Ellison's JUMP shots will be on display Wednesday through May 30 on the 4th Floor of the Dallas Central Library, 1515 Young St. Hours are 1 p.m. to 5 p.m. Sundays, 9 a.m. to 9 a.m. Mondays through Thursdays and 9 a.m. to 5 p.m. Fridays and Saturdays. Call 214-670-1643.
