How do I post pictures here?

Received an E-mail last night asking for a picture of how to layout 120 deg.s. Re-reading my instructions, it does appear a little vague. I spent some time on "paintbrush", and did a little drawing with instructions. Now I've tried to respond with this drawing, and I hope if it shows up there someone can do a better job than I. please post it here for all to see. No credit is due because this is just eighth grade math that I forgot before I graduated.
