From hobby to income?

One of my favorite hobbies is photography.  I'm certainly not a professional by any stretch of the imagination (I have friends who are), but I do enjoy taking pictures of my kids, my yard and my adventures in cooking/baking.  A few months ago, I decided that I really loved some of my pictures and that they might look halfway decent on the otherwise empty wall in my front living room.

I really love how this wall turned out.  One of my favorite photographs is featured in the middle:

Several other pictures are featured on either side, some from our yard and two from our trip to Massachusetts last October.

Every time I walk into this room (which is where my hubby is usually stationed at his computer), I stop to think about how proud I am of these photographs, especially since they were taken using the macro function of my tiny little Canon PowerShot SD1000.  I've thought about putting more of them up around the house, but I can't decide where to put them (it would look cluttered to add more in the living room, wouldn't it?).  A friend suggested that I should sell some of my photographs.  That thought has been stirring around in my wee little head for some time now, but I haven't actually done anything about it.

And then a sign appeared at the entrance to our neighborhood.
