   Vertical alignment<font size=5>...</font></a> </h3>
   <p> An image like
       <a href="#preview"><img id="imageAV1" onclick="eqntext('imageAV1')"
       src="../cgi-bin/mimetex.cgi?
       \normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt"
       alt="" border=0 align=middle></a>
       doesn't look as good as the same image
       <a href="#preview"><img id="imageAV2" onclick="eqntext('imageAV2')"
       src="../cgi-bin/mimetex.cgi?
       \normalsize f(x)=\int\limits_{-\infty}^xe^{-t^2}dt"
       alt="" border=0 style="Vertical-Align:-11px"></a>
       that's vertically aligned with your surrounding text.
       Along with several standard 
       <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html">
       HTTP&nbsp;header&nbsp;fields</a>, mimeTeX also emits a special
       &nbsp; <b>Vertical-Align:&nbsp;&#150;<i>nn</i></b> &nbsp;
       header, where <b>&#150;<i>nn</i></b> is the number of pixels
       (usually negative as illustrated) needed for a
       &nbsp; <b>style="Vertical-Align:&nbsp;&#150;<i>nn</i>&nbsp;px"</b>
       &nbsp; attribute in the <b>&lt;img&gt;</b>&nbsp;tag used to
       render your expression. </p>
   
   <p> But mimeTeX's special Vertical-Align: header
       is unrecognized and ignored by your browser.  You have to get the
       header, interpret it, and write the corresponding &lt;img&gt; tag.
       The only feasible way to do all this is using a scripting language,
       as illustrated by the following, rather naive, php code </p>
       <pre class="medium" style="margin-top:.5em;margin-bottom:.5em"
   >   &lt;?php
      $mimetexurl = "http://www.<i>yourdomain</i>.com/cgi-bin/mimetex.cgi?";
      function verticalalign( $expression ) {
         global $mimetexurl;
         // note: curl_init() stops at the first whitespace char in $url argument
         $expression = ereg_replace(" ","~",$expression); // so remove whitespace
         $url     = $mimetexurl . $expression;
         $valign  = "0";
         $ch      = curl_init( $url );
         curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
         curl_setopt( $ch, CURLOPT_HEADER, true );
         $gif     = curl_exec( $ch );
         $errno   = curl_errno( $ch );
         curl_close( $ch );
         if ( $errno == 0 ) {
           $fields = explode("Vertical-Align:",$gif);
           $vfield = trim($fields[1]);
           $fldlen = strspn($vfield,"+-0123456789");
           $valign = substr($vfield,0,$fldlen); }
         return $valign;
         }
      function mimetextag( $expression ) {
         global $mimetexurl;
         $valign = verticalalign($expression);
         $url    = $mimetexurl . $expression;
         echo ' &lt;img src="',$url,'" ';
         echo ' style="Vertical-Align:',$valign,'px" ';
         echo ' alt="" border=0&gt;', "\n";
         }
      ?&gt;</pre>
   
   <p> Now you can write &nbsp;
       &lt;?php&nbsp;mimetextag('\frac12\left(a^2+b^2\right)');&nbsp;?&gt;
       wherever you want to see
       <a href="#preview"><img id="imageAV5" onclick="eqntext('imageAV5')"
       src="../cgi-bin/mimetex.cgi?
       \normalsize\frac12\left(a^2+b^2\right)"
       alt="" border=0 style="Vertical-Align:-5px"></a>
       correctly aligned.  <!-- Besides making you escape backslashes
       (each&nbsp;&#092;&nbsp;must be written&nbsp;&#092;&#092;), -->
       This code calls mimeTeX twice to render each expression,
       once to get the Vertical-Align: header and build an
       &lt;img&gt; tag, and then again to render that tag.
       If you're a good php programmer and write better code,
       please email me a copy. </p>
   
   <p> If you're using mimeTeX's
       &nbsp; <b>-DCACHEPATH=\&quot;<i>path</i>/\&quot;</b> &nbsp;
       <a href="#options">compile&nbsp;option</a>, prefix your
       <b><i>path</i>/</b> with a leading&nbsp;<b>&#037;</b> and write &nbsp;
       <b>-DCACHEPATH=\&quot;&#037;<i>path</i>/\&quot;</b> &nbsp; instead.
       That leading&nbsp;<b>&#037;</b> won't become part of your cache
       directory's <b><i>path</i>/</b>, but it will signal mimeTeX
       to cache headers along with each image.
       Otherwise, the Vertical-Align: information is lost,
       and attempts to align cached images will fail. </p>
