The picture is what Jains do on Mahavira Jayanti, by parading around with images of Mahavira.
Mahavira Jayanti is the festival of the birth of Mahavira. On this day Jains will go to temples to hear the teachings and reading of Mahavira. Also on this day pictures and representations of Mahavira are marched though the streets with display and worship.
"Paryushana" means to stay in one place. This shows a time of thinking and ruefulness for a Jain believer. This festival has 8 days of fasting, remorsefulness, and pujas. On this day monks and nuns will be invited to give teachings to Jains from Jain writings.
All of India celebrates the festival of Diwali. Diwali has a special significance in Jainism because on this day Mahavira achieved deliverance and gave his last teaching. To celebrate Diwali parents give candy to their children and all over India there are lamps lit. Some religious Jains will follow what Mahavira did and fast for Diwali's two days. In 2013 Diwali will be on November 3rd.
After Diwali there is a very important festival called Kartak Purnima. This is an encouraged time for pilgrimage to the holy sites.
