First upload it. You can do that by going to Special:NewFiles. A link of that is placed on nav bar at the top.

After that, you can now place it on the image galleries or whatnot. If the section isn't present yet. You can look at other existing galleries, edit them so you can see the format. Then copy and replace it with the necessary info.
