I collect a lot of picture with flag of India decoration on this site. The resolution of all of the wallpapers are in high quality. You can use them as a greeting card design for Happy Independence Day. Such as this one, a tricolor picture with big Ashoka Chakra. This picture is an alternative wallpaper for Independence Day. The picture was designed in HD resolution with 1920x1080 pixels. You can also set this picture as your desktop background.
In addition to celebrate Independence Day, most of all Indian people doing several ceremonies. It is observed throughout India with flag-hoisting ceremonies, some parades and probably cultural events. Most of all Indian people also decorate their house, street, schools, offices and other building with Indian flag.
