how do i get rid of the white corners

[Susanna Prull]

i was able to round the edges of the photo, but when I used the photo
on a color background, you can see the white corners around the
rounded edges. How can I get rid of those so the picture looks
perfectly rounded on a color background?

Susanna, the only thing you need to do is make sure the photo is it's
own layer. Not a background layer (layer title is italicized and
locked). If it is a background layer just right click on the
background layer and select convert to layer or something similar.
