This creates a tooltip in IE but not in Gecko-based browsers.  For
cross-browser consistency you could add a title= attribute to the
<img> tag that contains the same text as the alt= attribute.

This may not be desirable if browsers treat an empty title attribute
(title='') in some strange way.  In Firefox it appears to be harmless.

People seem to like tooltips.  It would be an improvement to display
them in Firefox as well as MSIE.

To the right.

It certainly would!

I liked the PmWiki 1 behavior.  It was my main reason for holding back
an upgrade to PmWiki 2 for so long.

I think having an image float to the right by default would be a
welcomed improvement.  Most wikiauthors would probably be happy to see
text wrap around their (non-inline) images.

Maybe have the default-to-the-right behavior only happen when the
image is on its own line, like:

    Attach:image.jpg
    Some text.

being equivalent to

    %imright%Attach:image.jpg
    Some text.

Is that confusing?  Even if slightly so, I think the current behavior
of having text not wrap around images is more confusing, or maybe
"confounding" is a better word.  :-)
