Boarders for pics in Photoshop

[BenWall]

How is this done? and is there a way I can batch them as I have quite a few pictures, would like a white boarder.

Thanks in advance.

New Layer > Select > Modify > Border

Make that the top layer, then just change the ones underneath.

you can record a process then apply the process to a batch of images. Use the actions panel. Search in photoshop help 'actions' and it will give you a very quick and very simple guide! takes seconds and saves you hours!
