Fade to Transparency Help with Picture

I've been trying for hours to figure out how to create a fade to transparency on the top and bottom of the attached image... no luck whatsoever (using pixelmator app). I just want the top 15% and bottom 15% to fade to transparency.

If anyone is good at doing this, i'd love you forever.
