Yeah, I found this out the hard way myself.  Here's what I did to
fix it:

1.  Go to lenya/resources/kupu/apache-lenya/lenya/ and edit the
file kupusave.xsl.  You should see a chunk like the following:

<!-- this template converts the img tag to object
  for more, see http://www.xml.com/pub/a/2003/07/02/dive.html -->
<xsl:template match="xhtml:img">
   <object>
     <xsl:attribute name="data">

Towards the bottom, you'll see a couple of <xsl:if> statements
for the attributes @height and @width.  Copy one of them as a
template and replace it with @class.  So your bottom section will
look like this:

         <xsl:if test="string(@height)">
          <xsl:attribute name="height">
            <xsl:value-of select="@height"/>
          </xsl:attribute>
        </xsl:if>
        <xsl:if test="string(@width)">
          <xsl:attribute name="width">
            <xsl:value-of select="@width"/>
          </xsl:attribute>
        </xsl:if>
        <xsl:if test="string(@class)">
          <xsl:attribute name="class">
            <xsl:value-of select="@class"/>
          </xsl:attribute>
        </xsl:if>

Save the file.

2.  You'll see something similar in a file called content2edit.xsl,
which is in the same directory as number 1.  Make the same change
by adding in a check for the class attribute.  Save.

3.  Lastly, you'll need to go into each publication you have and
edit the file xslt/xhtml2xhtml.xsl.  Take a look at the patch of
XSL that starts like this:

   <xsl:template name="object2img">
      <img border="0">
        <xsl:attribute name="src">
          <xsl:choose>
            <xsl:when test="not(starts-with(@data, '/'))">

First off, I like removing the border="0" attribute from the image
tag above.  I don't like the assumption that it needs to be there.
I just like assigning a class to the image and assuming that the
CSS will handle whether or not a border exists.

Secondly, just like you did with the above two points, add a new
section for @class.  You can copy one of the <xsl:if> statements
from @height and @width as templates.  Save.

Now you're all set to have classes assigned to your image when you
save out of Kupu (and presumably Bitflux).  If you don't like the
default class names that Kupu uses, then you can go into the files 
lenya/resources/kupu/common/kupubasetools.js and
lenya/resources/kupu/common/kupudrawers/drawer.xsl and search for
the default class names of "image-left", "image-right", and
"image-inline" and replace them with whatever you choose.  Be sure
to add the classes you create in your CSS so that they float
properly and have the appropriate styles.

Hope this helps!
