Any Tech Savy Apple Girls??

I'm looking for my question about something that has to do with Apple products ...
So my iPhone went missing and i decided to erase it using Find My iPhone (had some inappropriate pics lol). Anyways the iPhone is offline so I am am wondering if someone connects to iTunes via computer, and doesn't connect a network to the phone. Will it erase? 
I'm worried who ever has it will share my photos or even just have them.
