Can someone add a white border around these 3 photos?

[techfestlunch&dinner]

SO im making posters out of these in a frame 23 x 33

but Staples only prints posters 24 by 36.

So if i add a white border thats 3 inches horizontally ONLY (no vertical border), i can cut it without losing some of the picture.

can someone easily photoshop that maybe? it would help alot! 🙂

oh and the third photo is 8mb and it wouldnt let me upload it so here the third:
