As part of the celebration of Flickr’s 10th birthday we’re putting a call out for a global day of Flickr photo walks! Let’s continue to celebrate 10 years of the best photo community by gathering with Flickreenos new and old and set out to document the world around us.

It’s all happening on Sunday, 4 May 2014, and we need you to help organize the photo walks in your area. Hook up with your favorite Flickr group or call on long-lost Flickr members who you haven’t seen in a while. Invite friends and family, invite people from your work, your social scene, or your virtual networks. Start a scavenger hunt, explore the history of your city or town, climb a hill, sail a boat, take pictures of bridges–whatever your fancy, join us!

How to get involved

• Join the #Flickr10 Global Photo Walks group and start a discussion topic for the area where you’re going to organize your photo walk. Feel free to ask any questions you have in the group discussions and share ideas for fun ways to organize photo walks.
• Go to the Flickr Meetup groups and find your city or region. If there isn’t already an announcement, start your own and let other Meetup members know about it: www.meetup.com/flickr/

Spread the word

*Share the announcement with your friends through Flickr, Twitter and Facebook.

*Remember to ask folks to tag their pictures and updates with #Flickr10photowalk. Adding this tag to your photo will automatically add your photo to the #Flickr10 Global Photo Walks group pool.

*Consider also tagging your photos with #Flickr10 and #YourCity (using the city where you are organizing your photowalk).

Tips for organizing a photo walk

Meet at a cafe, park, or public plaza — Be sure everyone can easily find the meetup location.

Pick a good time — We recommend starting around mid morning or mid-to-late afternoon. Aim for a 1-2 hour walk.

Make it short — A big group tends to walk quite slowly and it’s better to cover a small area really well than to sprint through a longer walk.

Have everyone tag their photos — Remember to ask folks to tag their pictures and updates with a unique tag (#Flickr10Photowalk) and the location of your walk so you can easily find the photos later.

Be prepared — Try to familiarize yourself with the area before the walk. You can also organize guest speakers to talk about the route or the photo walk’s topic like local art or history. This will help engage the others joining you for the walk and make it memorable. :)

End at an oasis — Pick somewhere that serves food or drink for the final destination of your photo walk and inquire if reservations are necessary. Share the location with participants upfront in case someone gets lost along the way or wants to join later on. Ideally it’s a venue suitable for all ages particularly if you’re expecting under-21s to come along, otherwise a nice pub is quite social as well.

Ushers – People walk at different speeds so it’s good to have ushers to keep the crowd together. Ask your friends to help or get volunteers at the start of the event.

Local residents — Some photo walks are going to be in and around where people live or work. Please be respectful and keep your group from blocking public access areas.

Accessibility – If you’re expecting participants who are disabled, it helps to pick a route that is short and is wheelchair friendly (the fewer hills, the better).

Be reachable — Share a contact phone number, email address or nominate a Twitter feed for updates on location.

Our last Flickr Friday theme was #ImOnlyHuman. This is a selection of our favorites from your submissions.

What does being human mean? It sounds like a question Hamlet would ask! Last #FlickrFriday you reconnected with your inner self and showed us different aspects of the being human: laughter and smiles, tears and loneliness, love and desire (for chocolate) etc. Some of you also thought that being serious is obviously very boring and played around with your picture to make us smile!

Check out all the galleries of favorites that you’ve been sharing with us, create your own and share it with us too.

The theme for next week will be #TheBusStop. In bad or good weather, on a road in the middle of the desert, in a deep forest or in a bustling street… there is always a bus stop somewhere! Take a shot of it and hop on board for Flickr Friday! Share your picture with us in the Flickr Friday group. The selection of the week will be showcased right here in FlickrBlog. Don’t forget to invite your friends to take part in the challenge by retweeting us, or sharing our status.

#FlickrFriday is a weekly photography project that challenges your creativity. For a chance to be featured on FlickrBlog, follow @flickr on Twitter & like us on Facebook and look for the weekly theme announcement every Friday. Browse the Flickr Friday category for more.

The Nasir al-Mulk Mosque in Shiraz, Iran, is one of the more visually stunning buildings in the world. The famous stained glass windows cast a rainbow of vibrant colors on the walls and floor of the mosque during certain hours of the day. View more photos of the mosque in the Pink Mosque’s Rainbow Colors gallery.

Windows can be open, closed, big or small — a simple opening in the wall that lets us discover a whole new world and touches our senses. Windows also show the unique personalities of the people decorating them: the weather outside, an everyday landscape or outstanding one. You made us perceive the world differently by showing us your amazing photos. Lean on the windowsill and take a moment to look at all the wonderful submissions whether they are of the world around us seen through a window or encourage us to imagine the life that takes place behind them.

Don’t forget to follow us on Twitter to see the next challenge directly in your feed. We will be back with the new theme next Tuesday.

Now that we’re two days away from the official beginning of the spring season, expect to see plenty of floral landscapes in Explore.

Our latest member of The Commons is the Tasmanian Archive and Heritage Office (TAHO). The TAHO brings together the collections and resources of the Archives Office of Tasmania, the State Library’s Heritage Collections and the Launceston Local Studies Collection to provide the Tasmanian community with unprecedented access to information about their cultural and documentary heritage to create more awareness, better understanding and easier access to the community’s documentary heritage.

The TAHO collections constitute a large and significant portion of the “memory” of Tasmania’s community. Additionally TAHO regulates the preservation and eventual destruction or retention of State and local government records in Tasmania and seeks to acquire private records which have long-term value to the community and best document the political, social, cultural, economic and natural history of Tasmania.

The TAHO joins with nearly 800 photos. The 25 initial sets include topics like The Tasmanian Wilderness, Tasmanian Lighthouses, Sports in Tasmania, and the visit of Queen Elisabeth II in Tasmania. We hope you enjoy the collection, and invite you to contribute your knowledge through meaningful comments and tags to the photos.
