“Feature Graphic” in Google publish Apps

Google announced the web version of the Android Market earlier today. It appears that the "feature graphic" is used (in a smaller size) for the top features (see large images near the top:http://market.android.com/) and at the top of individual app pages.

Tips:

• Use a safe frame of 924x400 (50 pixel of safe padding on each side). All the important content of the graphic should be within this safe frame. Pixels outside of this safe frame may be cropped for stylistic purposes.
• If incorporating text, use large font sizes, and keep the graphic simple, as this graphic may be scaled down from its original size.
• This graphic may be displayed alone without the app icon.

You can add app icon, app title, tagline, photo that represents the idea behind app, etc... Look at attached images for better idea.
