Anyone been in a similar situation and can give some advice? Can legal action be taken for this?

So, I was talking to this guy on Grindr and after he and I exchanged some photos and agreed to meet up the next day, he signed off and stayed that way for a couple of days. So, we didn't end up meeting. So today he messages me saying how he got his "beer goggles" off and was glad he didn't meet me, but was glad he got my pics so he could enjoy them and post them online. He blocked me a couple of seconds after sending this. Is there anything I can do? Isn't it illegal to post pics someone sends you to the internet like that?
