I uploaded your photo to my profile and worked fine for me, try to use this one:

 
if this above doesn't work, try this one:

 
Quick tip: when making those cover photos, try to make it bigger like 1920x1080 for example, this way you will never get trouble with your cover photo.
Quick tip 2: when uploading images, make sure it's a JPEG, because they lighter than PNG'S, the only thing is that JPEG don't support transparent background
 
P.s if you want you can remove the white part, but make sure to save as JPEG
 
Hope this helped
