I must say that buttercupmendes was fantastic and helped me with mine so I can’t take much credit!
I’m going to be using ‘Bye Bye Baby 3′ as an example.
1) You’re going to want to create a new page, use can do this by going into edit theme and it’s at the very bottom. Fill in the blanks and make sure to press the button that shows the link on your blog.
2) Next, you’re going to want to copy the imagines URL, you can do this by going into your blog, and right clicking over the title...eg. this title that I would click would be ‘Bye Bye Baby (3) (Sam Wilkinson) and you should get something that looks a little bit like this:

note: It is also known as a permalink
3) You’re going to want to go to your new page and type in whatever you want, for masterlists I use the title of the imagine so Bye Bye Baby (3) for this example.
4) Next, you need to highlight the title and click the chain that to me looks like an infinity sign, you paste the link into the box provided and click done and bada bing you have your first masterlist link!
