There is another way, it's supported but it's kinda strange. You can embed
those images not via the <img> tag, but via another embedding element. Try
using <object> and define some <param>s inside it with your params. Such
content model has only the <object> displayed. At the end you can insert
the img again inside the object as a fallback but objects are supported for
this.
Finally, try not worry about search engines penalisation. Content hidden
via CSS stylesheets and empty elements commonplace throughout the web.
Only, they are the worst as semantic web.

To Jarno van Driel: @longdesc is not only not supported, but also useless
for this purpose as extended semantics have to be present on the page
itself.
