I agree! I think the "Click to Show" is more respectful in general because it doesn't try to take people off the meme.
Basically you have to go to the meme that you want to have shown, click on the Show Embed Codes to the right, take the code from the BBC forums box, and paste those in the comment. Then as a finer touch, you can delete the unnecessary stuff from the front and back of it.
anona247 made a meme a while back with instructions about how to do it. Here's the link:

(I put the link to the meme in this case, and not the Click to Show, because the instructions are in the comments, and not the meme itself.)
