In case an image has transparency, like here, it's likely that the background would turn black. It causes some problems on images like that only contain dark colors, and when being cropped it looks like this.

If it will be possible in the future to give images with an Alpha channel a white or transparent background, or give it grey tiles (like the one that appears when hovering above an image in its file page) or perhas even allowing the local admins to pick a unique color, that would be really helpful.
