When you submit your application for certification for Windows Phone Marketplace, you need to provide screenshots of your application. Customers see the screenshot of your application in the details page of the Windows Phone Marketplace catalog on the phone and in Zune software when they make a purchase.

• You can provide up to a maximum of eight screenshots of your application.
• The screenshot should be a direct capture of the Windows Phone screen or Windows Phone Emulator. Graphically enhanced screenshots are not allowed.
• The screenshot must be of 480 x 800 pixel dimensions, and must not include the phone’s chrome.
• The artwork that you submit must be in .PNG format and can’t have a transparent background. Artwork with a transparent background doesn’t display correctly in the Windows Phone Marketplace catalog.

Note that you need to set the zoom level of the emulator to 100 percent when you create screenshots. This creates a screenshot that is 480 x 800 pixels.

When you submit your application for certification, apart from the screenshots, you also need to submit images that represent your application in the Windows Phone Marketplace. These include application tile artwork and an optional panoramic background art.
