Text String And I Want To Add text Automatically

Hello

I am trying to build up a CVS spreadsheet for my images,

I have my Product Code in A2 and the my image code in B2 (see below)

A2 B2
1234 1234.jpg

Is there any way of me being able to copy and paste the product code into B2 and Excel automatically place the .jpg next to it?

=A2&".jpg"

Cheers mate you have saved me a lot of time and grief lol
