The contest, called ‘In the Street: Europe in detail’, aims to reveal what ‘surprises, delights and inspires you day to day, just by walking down your street’.
The best three pictures from the UK will feature in the Flickr Calendar 2014, alongside winning images from France, Germany and Spain.
Prizes also include a £500 voucher to spend on photo materials.
The contest will be judged by a panel that includes Amateur Photographer technical editor Richard Sibley, after a shortlist has been drawn up based on a public vote.
The Flickr Calendar 2014 group is open for submissions until 20 October.
Three winners from each country will be announced on 19 November.
