People tend to put their best foot—and face—forward when online dating; I’m sure you do that as well. This may mean posting pictures that are very flattering but don’t necessarily reflect what some- one looks like all the time (or even lately). So I’d assume that any girl you’re meeting won’t be quite as hot as her picture— and if she is, then it’ll be a nice surprise.

But in general, if she doesn’t include full-body photos or if the pics look like she really had to scrape the bottom of the barrel to find them—they’re grainy or look like she cropped herself out of a big group picture or show her, say, too young to drive—let that be a red flag.

That being said, I sincerely hope you’re not basing your entire dating strategy on looks. Yes, you need to feel attracted, but attraction can build over time—have you ever suddenly “noticed” someone you’ve gotten to know who hadn’t really appealed to you when you met? And attraction can also fade over time if a girl’s hot but her personality sucks.
