Print lab asked to hang one of my photos!

Hello everyone,

Some of you might have seen me around and just to let everyone know, I've been into photography for only about a year roughly.  The print lab where I get my photos done has asked to hang one of my photos as a sample for customers to see. I agreed as he is always very nice to me and does my prints in a very short time.

I was surprised that he liked my photos so much to hang them. I don't know but I feel quite accomplished right now.

He made a suggestion to start selling my photos at galleries, but I don't know the first step to start selling at all...  He also said a good idea would be to start selling them on the streets of Times Square.

Where do I even start if I wanted to get into the whole gallery thing? Are their easier or better options available? What are some of your thoughts on selling prints.  He gave me the encouragement I needed to know that I've got a knack for this
