well the easiest way for me is maybe the long way ..I just hit

open what you want to take a picture of ..click mouse to make sure that window is selected

then use the keyboard keys -- alt + print screen

then go to start and run
type in mspaint
hit okay

then i hit the ctrl + V button, on the keyboard , and it puts your picture there in mspaint. then i hit the dotted square box and use the mouse to make a box around the image

then i go inside the little dotted box, put the little dot box around things you want in the picture , i made and left mouse click and pick copy

then i go to file and new and it opens new box
then i just hit ctrl and V, on the keyboard ...it paste it
then i just go to file and save and i give it a name and then make sure it says save as .jpg.

that is just one of many ways ...to just take a pic real quick too post

you can also render a pic but that is alittle more complicated ..hope this helps .confused just let me know. this way can be use to just get point across i use this method ... unitil i am totally finished with project then i do what is listed above or a few other methods
