Safari Rendering image background black on load

Question

I'm currently working on a website and having an issue with Safari. When loading an image there is a black background that is placed as a stand in. I would rather this be transparent or white, but I can't seem to figure it out. Check it out:

I've made html and body have background-color:white; but this doesn't seem to have changed the issue.

Answer 1

Just save the PNG image with interlaced option

Answer 2

I had the same problem in safari 6. My image was in grayscale color space. I switched it to rgb and the problem disappeared. Try to check your images color space settings!
