I have been playing with Flickr the last few days trying to figure it all out. It seems to be fairly easy to work with IF you know what you are doing. I have not learned all about it yet so am having a bit of frustration trying to get pictures from one place to another. It is not too complicated though once you learn where everything is. We used to take pictures with a camera, take the film out, take the film to the store for developing and in a few days pick them up. After that they either ended up in a drawer, a box or if I was motivated in a photo album. This is much the same only with digital images. Pictures are taken, downloaded to a computer and Flickr acts kind of like the drawer or the box. When you want to share the picture you can pull it out and put in on a blog or some other site for sharing.
I chose this picture of my kitty Salem to share in this blog. I had a bag sitting by the door with my book in it to take back to school the next day and he crawled in. I couldn't resist taking his picutre with the Breaking Dawn book. This is a very popular series at our school now and so I downloaded the picture to my e-mail and accessed it at school so I could use it to make book marks and a poster that said "Curl up with a good book". It was fun and the students loved it.
Pictures, blogs, Flickr account have so much potential for use and it is fun, but, alas, it takes time!
