DB-HTML how to scale down too wide imgages (without attr in imagedata)

hi,

im just customizing the docbook-xsl style sheets for HTML output.

i got some images that are too wide for to be displayed in the browser.

is there a way like set a param to "800px" and each image surpassing this
width will be scaled down?

or, if not, is a template possible / existing in the sheets that returns the
width of an image?


thx in advance,

seb
