Thanks for reply. I cannot really change the citation style. Sometimes I have multiple citations in a row like "[1,4,5,6,89]". I cant even imagine how to replace these with special character. Having a quote from citation in the text is not an option either.
Thanks again. I guess I'll just stick with what I have.
So you think number images will not work. Something like
<sub><a style="speak:none" href="Footnotes.html#ref1">[<img src="one.gif" alt="1"/>]</a></sub>
will not work?
