LG VX-4600

I wouls like to know how to insert a picture to my 4600. I hate wallpaper backgrounds, I would love a simple white background (it would be good to have a wallpaper option 'off' or 'none').

I have no experiance, no cables, no idea, no nothing....

Can somebody please give me step-by-step info (or point me to a website) how to edit a new pic and how to download it to my cell phone?

Thanks!
