Just thinking:
Sometimes, there's an image which is not very wide. You don't want it to occupy a whole line, because that would create a huge white space. So, you'll align the image left or right from the article. (I prefer right, so the text of the article will align left).
Now that image has a caption. The caption would be wider than the image, which looks ugly, so you want to wrap it. Also, the caption should be centered with the image. What I do is
<table align=right> <tr> <td align=center width=1> [[image:xyz.jpg]]<br> Some longer caption, which is wider than the image itself </td> </tr> </table>
Someone explain to me how to do that in wiki syntax, with the *same* result, without the code looking more ugly? (you are free to invent a wiki table syntax for that puropse!)
