Here are some more of our readers' pictures, this time on the theme of playtime. Each week we ask you to submit your pictures on a set theme and you can see the ones I have selected here.
Many thanks to those of you who sent in your work.
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: Missing
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 "missing" in the subject line of your message.
The deadline is midnight GMT Tuesday 12 April 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.
If you want to plan ahead, you can see a list of the upcoming themes here.
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.
