Pictures as hotlinks

Hello,

I've got a little problem here with
big pictures (mostly in <figure>-tags) in html-files.

Since I use a cms for publishing my
docs, there is only a restricted width for pictures so I want to use smaller
ones and make them to hotlinks to the original version.

Is there a possibility to work around
the limitation for xlinks which as much as I know only work for inline-elements?

Thanks in advance for any reply!
