1.uploading-
you can upload photos directly from your cameraphone into Flickr? There is an email address set up for you, just go to this page. Enter the email address into your phone and send! Make sure you have email on your phone plan or it won't work.
2.communities-
Look around, see whose photos you like. Check out The Flickr Blog, which has great photos daily, or keep an eye on the page with Everyone's photos. Or better yet, invite your family and friends to see your own photos, so they can leave notes and comments and tags for you, and give you photos from your own life. Having friends, family and favorites on Flickr is probably the thing that will make the biggest difference for you!
3.blog-
Flickr and blogs.First, set up your blog. It can be LiveJournal, Blogger, Moveable Type, Typepad or whatever. Make sure you like the layout of the post. If you know HTML you can tweak it to make it look the way you want. Then look for the little "Blog This" button on the left side of the photo on the photo's own page. Click it and away you go!
You can also add one of those cool photo strips to the side of your blog. Just design your badge, and cut and paste the code to your blog template! And another cool thing you can add to your blog is the Flickr Zeitgeist. Cut and paste to your blog. You can even set it up so it just shows your pictures and those of your Flickr contacts.
4.Securely Share Private Photos-
When you upload photos, you can check the box that says "Public" or "Private". Private photos are completely hidden from everyone except you, but if you want to be visible to your family or friends, check those boxes. You can change the privacy of a photo at any time by clicking on the red (for private) or green (for public) button on the photo. Another thing you can do is set up a private group and invite your friends and family to join it. If you invite them from the group's page, they are automatically made a member. You can then add photos to the group's photo pool that every member of the group can see.
5.RSS and Atom Feeds-
RSS is a way of getting your photos to the people who want to see them. They "subscribe" to your feed and get all the photos you publish, in whatever way they want to view them. If you're not familiar with what it is check out the BBC's handy What is RSS? page.
Flickr provides RSS feeds for:
Everyone's photostream
Group & forum discussions
