XSLT question

I have an existing xslt document which has a xsl:when statement followed by an xsl:otherwise statement. Within the otherwise statement, it calls a few templates that build tables. What I want to do is tell it to create 2 tables with an optional image. I know I can do this by saying insert 2 tables or insert 2 tables and an image, but is there some way I can consolidate this and say insert 2 tables and an optional image?
