Pretty much the same way as on computer, but you have to be in "desktop" view. You enable desktop view by going to the very bottom of the screen, and you should see a "desktop" link. You click it, and you should be viewing your Wiki just like you are on a computer. And the process is pretty much the same for uploading. I think you need to "name" the file-space you want to take though, because if you don't it'll just name it by default like "Image.png".
