Save the picture to your computer then right click the photo and choose "open with" then choose a program like Paint, Photo Editor, etc. Once the photo is open in this program then go to "file" and choose "save as". When the "save as" box opens you will be able to choose "file type". Here you will change it to a jpeg. file then click "save".

Not really up to all that jpeg and gif stuff.I do picture's by guess work alot,work's so im happy. Try this when you find a picture you want,right click it and click copy or send,to desktop.That makes a shortcut then i add it to my picture folder or you can right click on picture and click background,and i alway's get the background. Some are larger then other's i guess that's the jpeg stuff.Just don't be affraid to click on something and try what you don't know, that's how i learn.
You can only use jpeg files for 360 backgrounds...your frfiend must have came across a jpeg fiel that words.
