Firstly, telling someone to f* off when they are trying to help you is the wrong way to go about it. Rethink your attitude, please.
There's no reason to have an 1000x800 image. osu! runs internally at a sprite resolution of 1024x768. If you WERE to have one image larger than 640x480, having it more than 768 pixels high would be pointless (unless vertically scrolling). 1000x768 would make sense if you were horizontally scrolling (and only then). 960x768 would make sense if you are displaying it as a background which fills the horizontal length of the screen (at a scale of 1.06666667).
Edit: If the image was 1024x768 (as in, 4:3 aspect ratio) AND you weren't using the background image in the storyboard, then this would be marginally acceptable under the same premise I allowed Jarby to do so.
If I was a mod attending to this map I would make a note never to visit this thread again. If any of the people that have helped you decide to continue doing so, you may want to thank them for dealing with your personality.

EDIT : Should I resize all to below 1024x768 or keep it?
