go to properties and highlight the address and click Control-C to copy the link into your clipboard and then paste the address of the pic whereever you like
It's against flickr rules to do that. Just so you know. To read this on flickr, you go to the photo. Click "all sizes", then scroll down. Option two is what has to be done for these boards. It states:
Remember! Flickr Community Guidelines specify that if you post a Flickr photo on an external website, the photo must link back to its photo page. (So, use Option 1.)
Anyway love flickr. but, I also have a photobucket account, just for that reason. When you upload there, it gives you the url to post for bulletin boards. Works like a charm. I use flickr for my blog, and all other reasons. I use photobucket for the DIS.
