Please please please please please!
Have those black bars FULLY minimized when viewing an image.
Opening an image pulls out the black bars which are constricting the image, making it impossible to see it in all its glory because 1 centimeter is cut off from both ends. I'm talking about the top bar with the extra buttons like ZOOM/DOWNLOAD and FULLSCREEN along with the bottom bar which contains the title. Why do we need these bars ? On PC all these functions already exist. Right click to download image, ctrl + scroll to zoom. On mobile, two fingers to zoom, hold the finger to download. There's no point in this obstruction of an image that is being forced upon the image. It may not sound like a big deal to you, but it is a big deal to people who appreciate images.
Also it's quite ironic that there's a FULLSCREEN button available which once again does not remove those black bars at all. It's contradictory to the whole point of clicking on an image. So please... minimize the bars or add an option for users so we can choose to have it minimized by default.
And please bring back the option to choose a mod's header image from already uploaded images.
