How do I block SmileyCentral banner ads?

[Jennifer Marx]

My members are using smiley graphics from SmileyCentral.com and annoying banners ads are getting inserted in the posts, unbeknownst to the poster. I need to get rid of these banners. Here's an example of a post with a banner ad on our boards:

I found a discussion of this issue here:

But I'm not sure how to implement the suggestion. Can anyone help?
