Up to now there are only the high resolution images (JPEG). The low
resolution images have to be created out of them and I plan to use
JPEG format as well for them.

Iīm thinking of using the "role" attribute of "imageobject" with a value
e.g. īrole="lowres"ī and write a custom stylesheet to select this
"imageobject" if one with this attribute is present, otherwise use the
high resolution image.
The SGML source would look like:
<mediaobject>
<imageobject>
<imagedata fileref="images/image00.jpg" format=jpg">
</imageobject>
<imagedata role="lowres" fileref="images/image00-low.jpg" format="jpg">
</imageobject>
...
</mediaobject>
The modified stylesheet has yet to be written :)
Is this a possible solution?
Another idea was to always use the second "imageobject" for the low-res
case and select this in the HTML-stylesheet. But I think itīs not a good
idea because I would have to edit the SGML source in this order.

This is exceeds my DSSSL knowledge by far at the moment...
