Now to change wallpaper Nikon D40?

Bought my Nikon D40 from a friend as a starter camera, didn't come with booklet.
Read up on the settings, controls, etc.online but couldn't find how to change the wallpaper.

This is annoying, please help.
Added (1). There's a wallpaper, just like computers and cellphones.In the background.It's a picture of the friend who sold me the camera. She doesn't remember how to change it though.

No, I'm not talking about the image previewing.

Look it up. Every site that discusses the Nikon D40 features has mentioned this but hasn't given me the option to change it.

It's ridiculous and reduces image setting display size.

I don't need anyone to tell me that there's no such thing, because there is. And if you aren't familiar with this camera don't give useless answers.

Someone please help..):

Tips on shooting a first time wedding?

A good friend of mine likes my model photography and asked me to do her wedding. I told her yes, I really want to be confident while doing this. I have five months til the wedding. But my biggest concern is dealing with a new camera. I'll be getting the Nikon D3200 or 5200. (transitioning from Canon.) and also, low light is my biggest downfall.

Please as many tips as possible! Also any essential equipment I might need with me. Bare minimal, at least.

Thanks to all. -Mandy!

Nikkor Micro 40mm for landscapes and everyday photos?

I wanted the D5100 kit lens for landscapes and the 40mm for macro. I just don't have enough money.So is it a good choice to skip the kit lens and use the 40mm for macro, landscapes, and even evryday stuff? And is the fact that the lens is prime a big disadvantage, or is cropping going to make up for that.
