I think when downloading images with a transparent background, it could be a nice option to give users the option to pick a solid color to fill the background with. For example, you could download the image on a white or black background, or pick a custom color

I sometimes need to find a logo etc. on a solid background, but the only available good images have a transparent one, so I have to download it and manually add a background. Would be cool if this could be built in.
