1 - Copy the image to your PC, to do this place your mouse cursor over the image, press the right hand button on your mouse, a small list of options pops up, select 'Save image as'......
A new small window opens, just type the file name BCUKavatar (all one word).
You will see at the bottom of the small window where it says 'File name' ....the name already highlighted in the box (3742993229_c729206af2_o.jpg) will be over written with what you typed, do not worry this is normal.
Now you need to select where to save it.....save it to your 'Desktop' to do this select 'Desktop' on the far left hand side of the window
Now select 'Save' at the bottom right of the window.
We are saving to Desktop so it will be easy to find in the next steps...
PS - no specific reason for the file name I just like the bleedin obvious
