// One thing I do to keep my Netflix queue populated is I go to IMDb and look at the top rentals
// lists.  From there I will copy the name of a movie and and then paste that name into Netflix's search page.
// It's a very tedious operation.  This script creates links in the IMDb pages that will do the work for me.  
// Now when I go to IMDb, movie URLs will each be followed by a 
// "(Netflix)" link that will take me to the Netflix search results page for that movie.

// Problems or comments?  Send me an e-mail: ed@artefxdesign.com
// For greasemonkey info: http://greasemonkey.mozdev.org/

// 4/3/2005 - I fixed a problem where the Netflix search string would be the word "null".  I also 
//   removed the target attribute from the inserted links.  Now you can use the back button to return to IMDb's site.

/* 
	5/9/2005 Thom Wetzel (www.thomwetzel.com) modified the script to 
				add Blockbuster links rather than NetFlix links to IMDB.

	------------------
	Modified the code again so it doesn't need an external server for the 
	BB icon.  I'm using a data:image/gif as the src for the image and the
	image is stored inline.  
	
	I used http://software.hixie.ch/utilities/cgi/data/data to generate
	the data.

	Fixed to work with both Trixie(IE) and Greasemonkey(Firefox)
