Finz,
Scroll to that post and hit Quote. You'll see a URL inside some stuff like "img src." Copy that stuff down. Find an image online, right click on it to copy the image's URL, and enclose that URL with the img src etc stuff. One caution -- if you do this in word, Word may give you left quotation marks and right quotation marks instead of plain old bisexual (ahem) quotation marks. You need the plain ones for this to work.

Save this info somewhere. I've got a few more details to add, which I'll do later.
