Posting photos?

I need some help. I tried, unsuccessfully to post a few pics. I used the photo icon and pasted the URL - but it did not work. For reference, here is a sample URL I tried:
http://www.flickr.com/photos/8278804...in/photostream

Any tips on what I am getting wrong?

For starters, the picture link requests a yahoo log-in. Since it's secured, it likely can't be linked directly.

I am now loading the photo to imagecoast, took me a while to remember but I had exposited photos from there before.

The following thread has a lot of helpful information on this topic...
