This script is made to easily generate some HTML code to insert pictures from flickr into your blog posting. That html code will represent a 2-row table having a small version of the picture in the first row and title and author as caption in the 2nd row, including a link to the original photo in flickr.
See my blog here to see an example how it finally will look like.

To generate that html code simply click on the Greasemonkey icon in your firefox browser when visiting a flickr photo page and select "User Script Commands ..." and "Block this flickr photo page" from the pulldown menu.
