Editing uploaded photos on Facebook?

[jessiebelle96]

I just got my license yesterday, so I Instagrammed a photo of my temporary driving certificate, and linked the photo to Facebook. While the information (full name, address, etc.) is visible on it, the font is very small so a person couldn't easily read it; however, it's still possible.

Is there any way that I could crop the photo while it's still on Facebook? Or could I replace it with another photo without deleting the likes & comments? I have made my Facebook as private as possible, but I still want to be safe. Thanks!
