title: Magnific popup transparent png as grey
body: <p>I am facing problem with magnific popup - when transparent PNG opens, the transparent parts are grey. I have searched for solution but without success. While changing img.mfp img background color to white it changes but it shows the white color and that is not good for me. I need to have it just like the whole background - black with opacity 0.01 (if I am not mistaken)...I did not changed any relevant code in CSS or JS related to Magnific popup.
  Can anyone help? Thanks in forward</p>
