How to insert .jpg after each entry in a column

How to insert .jpg after each entry in a column. I have a column of 100 part numbers that i need to add ".jpg" extension to so the pictures will appear in a browser. How do I do this in one simple command, so I don't have to edit each field one at a time?

With your first part number in cell A1, enter in cell B1

=A1 & ".jpg"

Then just autofill down, delete column A if required. HTH.
