Creating an image directory using a macro

Hello Experts, I have a macro file that creates a image chart using a set of data that changes with each selection from the drop down boxes. I am needing to place another command button to the userform that when selected it makes a JPG image of the current data on the chart and labels the image chart with the 2 values it is comparing each other with? So let's say its "eTemp vs. TGF" when the command button is selected it takes the image that was created and puts it in a directory folder of my choice with it being named to what the 2 values are compared against each other and maybe with a time stamp afterwards?

Any help with this would be greatly appreciated!
