Had a woman tell me I don’t look like my picture?

So just started a new job at a large tech company. I updated my profile picture for outlook/email. I spoke to an executive who I shook hands with on my first day, don’t remember her but what’s so strange is today in a conference call, she tells me “wow you look NOTHING like your profile picture” I’m a little surprised.. I mean I’ve gained about 30 lbs after having a baby, but other than that and a few dark highlights in my hair I can’t even wrap my brain around that.. PLUS why would you say that to someone? I just tried to play it off and say “oh really? Gosh maybe it’s my hair” and laugh it off but It’s really messing with me.. do you think she was just trying to be caddy? or maybe there is some legitimacy and she’s just a person who has no filter and openly says that sort of stuff? So odd would appreciate any opinions
