Unique Legend Image and Line

[nettesheim2]

I would like to plot 2 curves and, in the legend, have a unique image for each curve and the corresponding curve color to show which it belongs to.  I cannot figure out how to replace the text "Curve 1" or "Curve 2" with a sample of the actual curve, as you would usually see in the place of the monkey/giraffe in my case.

I don't have  a great grasp on the handler, but I have enough to create the following code. See the attached image for clarification. To reproduce, you can download a monkey and giraffe png (monkey.png and giraffe.png) into the same directory you run the code in.

So instead of the legend showing:
image1 "curve 1" (where "Curve 1 is the actual text"
image2 "curve 2"

I would like:
image1 curve1 (where curve1 is a segment representing curve 1 (green line)
image2 curve2

I appreciate any help you can offer!
