Is sending a pic to Twitter just like sending a picture to anyone?

So, I sort of know how to send pictures from my cell phone to Twitter, but is it just as if you're sending it to a real person? I got my email thing that I have to send it to, so do you need to go online on your phone to send it? Or do you just send it as a regular text? And, do you still have to pay for it? If so, do you know how much it costs? Thanks!
