Your pictures of the week: Black and white
Each week we ask our readers to submit their photographs on a set theme, this week the subject was black and white.
Thanks to everyone who submitted their photos and congratulations to those whose were selected.
If you'd like to see one of your pictures on the BBC website then take a look at the upcoming themes, grab your camera and start shooting.
Next week's theme is: Movement
Interpret this in any way you see fit and send your pictures to us at firstname.lastname@example.org or upload them directly from your computer.
Please include the word "movement" in the subject line of your message.
The deadline is midnight GMT Tuesday 15 March 2011, and remember to add your name and a caption: who, what, where and when should be enough, though the more details you give, the better your chance of being selected.
We will publish a selection of your photos this time next week.
Files should be sent as JPEGs. They shouldn't be larger than 10Mb and ideally much smaller: around 1Mb is fine, or you can resize your pictures to 1,000 pixels across.
Please see our terms and conditions, but remember that the copyright remains with you. The pictures will only be used by the BBC for the purposes of this project. Finally, when taking photos, please do not endanger yourself or others, take unnecessary risks or infringe any laws.
