Got a txt from this number saying check out my pics on "sharepicsinfo.com"

I just got a text from this number saying "it's danielle www.picshareinfo.com look at my pics on there. Who or what is this?????

At 1:19 A.M. I received a call that woke me up from my iphone. It had a message from Danielle.and to open if 18 years old.  i have a granddaughter at church camp on a mission trip with a Danielle and being 1:18 in the morning I thought maybe it was something wrong. I opened it and it was porno pictures.  How can I trace this and not ever have it happen again. It burns me up because of the pictures and the time also..
I called back on my home number and it said the number is not in service!
