If it's your background Profile photo @QuittingGirl you're talking about, what I do is I pick one that is suitable for an extreme landscape format & I size it prior to using it doing that in "paint". Then I place the photo in my profile background and move the image around in an effort to capture the subject matter I want to show.
Because it's a extreme landscape formate you can never fit the entire subject matter of your photo in there.
I've attached mine below. There's lots more image in the photo I chose but most of the important images are lined up for an extreme landscape viewing format.
The key is picking the right photo. One that has interesting subject matter in a narrow band across the photo.
