Sending Photos

I have the RPI3 Model B & Hologram Nova which I can successfully send sms messages from the CLI on the RPI3 to a cellphone. What I would like to know is if I could send jpg photos to the cellphone as well. And if so how?

I’ve read something about the socket and rest api, encoding and decoding base64, twilio sdk, and writing at commands but they were all on different topics. Not sure if and how it all fits in.
