What do u mean disappeared?

You can either upload a file and it'll keep it's name or you can manually change it in the section that says "Destination filename" on the upload page.

If you're image doesn't follow image format advice an admin or helper will rename the image. Otherwise images can be deleted for various reasons. Perhaps this is what happened to the one you uploaded?
