The run-up to Mardi Gras (Shrove Tuesday) means one thing - Carnival season. This is when big street-parties take place around the world.
One of the most famous takes place in Rio de Janeiro, Brazil. Here the King of Carnival presented the keys of the city as a symbol to mark the start of the week-long celebrations.
Revellers covered in foam dance in the streets in what is traditionally a Christian time for celebration before the more serious period of Lent begins.
Venice Carnival is famous for the elaborate masks, costumes and fancy balls which take over the streets and canals.
Mardi Gras has given residents of New Orleans a good excuse to celebrate since Hurricane Katrina hit their city in August. This Batman float works its way past the cheering crowds lining the streets.
