Something about image centering

<span class="equation"><img.... /></span> should centre an image inside
the containing paragraph/div/whatever with the .equation styled as
text-align= center shouldn't it? It's not working for me and it's
starting to drive me a little bit nuts... Advice would be appreciated.

No, it shouldn't. Unless you play around with float or display, span
elements are inline and the text-align property doesn't apply to them.
(Since the width property doesn't apply either, and the element shrink
wraps its content - there isn't any margin for centring anyway).

So I have to wrap each equation image in a block-level element like p
or div? Fair enough. Thanks.

Yes, anything else wouldn't make sense as you wouldn't have any space to
centre the image in.
