How do I combine 2 pictures into 1 and save it as one jpeg picture in
corel paintshop pro?

Example:  I have a picture of a box, next I have another picture of
the item.  I need to put 2 pictures into one, so that the item is on
top and box at the bottom, then save it as one picture.

Not familiar with this program but all graphic programs have more or
less the same characteristics.

Open both files- from your tools choose 'clone' (make sure under view
you've selected "tool options" as being visible and choose multiply
-play with the options there-) - right click on the graphic you want
to duplicate then click on the first one and slide your mouse around.

You may want to change the amount of pixels your clone tool duplicates.
