INSTAGRAM HELP! (Pics inside)?

[Ash]

Two things:
How do I make a picture have a white background instead of a black when the photo is smaller than the picture box? Like a thick white space, picture and white space again instead of the whole picture in the square?

And also how do you take a picture, and put it got next to the same exact picture just flipped?
