LG Voyager VX-10000

I just got the Voyager. I must say this phone is the perfect fit for my hands as they are kinda big. At any rate......I have added my email account to the mobile email application and I have 2 questions....First off if someone sends me a pic to my email how can I if possible take the pic out of my email and add it to my phone as wallpaper. Also when I download music can I use that song as a ringtone!!

Thanks for the help
