In pictures: Power

Each week we publish a gallery of readers' pictures on a set theme. This week the theme is power, and we start with a photograph by Pearse Healy: "The power of a human arm. Taken as part of a body and movement series, as a reminder of where it all comes from."

Tony Clements: "I shot this picture of The Shard on my way home from work one night, I felt very small looking up at the sheer face of such a huge, powerful building."

Dorothy Ogilvy: "Is it possible? I took this picture a long time ago and filed it under curiosities because I never have been able to work out how the ladder stayed upright. The seemingly acrobatic electrician from EDF is repairing a wire in rural France."

Tom Barnes: "The mighty eagle - It was hard to imagine the power and strength of this bird as it stood on my glove."

Tacia Carlin: "Who has the power?"

Fabio Romano: "The power of the Roman Empire."

Julia Law: "Aphroditie's Rock in Cyprus at Easter."

Steve Thomas: "I was out for an evening stroll the other night along the River Walk, Witham with the family, and noticed the power lines of the main Norwich to Liverpool Street railway silhouetted against the evening sky."

Pauline Richardson: "A lot of power is required to light up the Bund in Shanghai."

And finally a picture from Baldev Sahota. Next week the theme is darkness, and the deadline for your entries is 9 August. If you would like to enter, send your pictures to yourpics@bbc.co.uk. Further details and terms can be found by following the link below this gallery.
