Image Document Background Color & Image Position

I am writing on photography, and use a lot of images in my text. I’ve created individual picture objects (hundreds of them) under research, with links in my text, so that I can write in one window and move between images in another.

This would work perfectly except for two small but irritating problems. First, and worst, the light blue background of the “Image Document” window is not a neutral background, and in some instances it effects (changes) what I’m looking at. Second, the image defaults to the center of the document window, when it really should go to the top. (The second issue makes the first worse, since the centered picture appears more surrounded by light blue than one positioned at the top would.)

Is there any way to change the background color and object orientation settings for the “Image Document” window? I have looked, and also looked for suggestions here, without success.

Thank you.
