When you upload something with the same file name something will pop up saying there's already an image with that name. You must rename your picture otherwise you'll get something like this happening to you. Angry users.

By same files names this is what she means:

Sky.jpg and Sky.jpg (just an example). If you upload a picture called Sky.jpg, you must change yours to I don't know, Fairytale.jpg instead.
