Losing images after going page set for https

I had a lot of problems with https picking up the wrong path. Finally got that sorted out through the use of the reset code, but now after I visit my one page that I want to have as https, I lose my header image on the page set to be https. I’m guessing it’s got something to do with perhaps the image not being https? How do I manage to get it stored that way?
