How to change an ugly background in pictures with Fotoflexer "for the beginner"

Have you ever looked at at picture and WISHED you could have a different background? Yeah me too, and no I'm not talking about all kinds of complicated stuff, palm trees, or the moon. How about just having a plain solid color background?
For our cake business, we take LOTS of pictures, and since my mom is usually the one taking pictures, I'm often left with a very messy cluttered background for a really beautiful cake. Until I get the photo box made, which obviously needs to be on a much larger scale due to the nature of what we will be photographing, I'm stuck with hundreds of pictures, that need editing. 
I know there are programs out there that can probably do this with a click of the mouse, with very little effort on your part. I don't have any such programs, and am a TOTAL BEGINNER. Even then I managed to do pretty good, and I'd like to show you how I did it. 

Here is the before picture of this really cool graduation cake she did. Notice the background? The mixer, the hooks, the crap back there. Hardly does anything to showcase this cake right? 

Ok, now you have to see what I did with this picture. It's nothing really spectacular, but it is a HUGE difference, and I really want to hear what you think!!!
