It's uploaded! What now?
[edit]When your upload is complete, you'll find instructions for how to use the image elsewhere. The name of the page, where you can always find the file, is whatever you named the file when you uploaded it (including the file extension).
On Wikipedia, you can add an image to an article easily. You can do this through VisualEditor (the "edit" button) or WikiCode.
