Got this from a friend...
Take your username and change all the letters to numbers i.e. a=1, b=2 etc. then add those numbers together--- mine was 139
The add those numbers together -- 13, and find the journal entry with that number (so in my case my 13th entry). If you don't have one that high, then add the numbers again and use that new number.
Then take the first number (ex. 139) and count the letters into the journal entry. Take the word you stop in and type it into google image search. Pick an image from that page and post it here.
