Of the codes listed on the site, this is the one you need -
http://picometer.writertopia.com/words=10000&target=20000
The first number (10000) is your current count, and the second (20000) is your total.
Set the numbers to the right point, copy it, and then click "insert image". Paste the code into the box and click OK. Hit preview and you SHOULD see the box below:
Note - when pasting into the "Insert Image" box, make sure that you delete the "http://" text that's already in there, or you'll confuse it (because you'll have 2 https) and your image won't appear.
Hope that helps! I find that having to update the word count every day encourages me to write more.
