Indicate that page images are still loading

Currently, when page images are loading, they appear to be blank (i.e. white). It doesn’t look like anything is happening.

A loading indicator should notify the user that something is happening.

JPG images can be stored progressively which would not result in blank but pixelated images at first. It would serve as some kind of loading indicator.

I don’t think a loading indicator is the correct choice, as it might have detrimental effect on perceived performance. We have the following choice:

• Leave it as it is: Loading images will start with a white background, building up the image from top to bottom (except when using progressive JPGs). This is a loading indicator already.
• Use a dedicated loading indicator that hides the partially loading image until it is completely loaded.

Do we still need this? I’m not convinced we need a loading indicator for all loading images.
