When on my iMac I'll grab an image and shrink them to 300x300 so that when a contact calls me, their picture shows in the top right corner of the screen. If I select a photo for a contact from my iPhone, when the person calls me the picture takes up the whole screen and is very blurry. How does it look in iOS 7 when someone calls you? Do you guys use the small picture in the top right or have your pictures take up the whole screen? Since I made all my contacts' pictures 300x300 will that cause them to look blurry in iOS7?
