Need Help: 240v in Garage?

My dilemma is I know basic wiring but not sure anything above a standard wall receptacle or light switch, lol.
I'd like to put a 220/240 plug or two in the garage but I'm not sure if it would support it. The bottom of the breaker box says 120/240v but I'm not savvy on capacity stuff.

Be safe and call an electrician.
At least have a professional come out and look at what you have.
Safety first...learn not to burn...your house down:)
