I'd just like to create a simple white border around this picture, without shrinking it. I tried creating a new layer and expanding it beyond the borders of the original layer.
At first, I was unable to resize as it was transparent and I was told "no pixels selected." So, I filled the layer with white, put it in front, and tried to Cmd + T / Transform it that way. It seemed I was making it bigger, but the white did not expand with the border, nor was I able to refill the whole thing with white.
Any idea where I'm going wrong, or what the easiest way to do this is?
Thank you in advance.
