I use the SAVE COPY AS option in my PSP because it allows you
to save the work and keep it active in your work space in PSP.
This is good if you need to look at an Avatar in your chat program or at
a web page graphic to see if you like it or might need to adjust it.
If you do it's there to continue work on just make the changes and resave as
the same file name...if no changes are needed just close it out and and if asked
if you want to save the image 1 say no....it's saved under your file name for it..

Again this is one of the tools I have on my customized tool bar I use it
every time I save so I need it handy.

The screen shots set it up for you and explain the process if you need help with
it find me when I am here and I will be glad to help you.

Good Luck.
