If a person had for example around 3000 jpg files, all called
fredbloggs.jpg, junebloggs.jpg etc.

And wanted to change them to SITE1FB1.jpg SITE1JB1.jpg

How would one go about doing this ?

I have the list of names in rows in an excel spreadsheet column1 being
what they are now and column2 being what they should be.

Is there a quick and easy way ?
