Although I appear to be having a conversation with myself - I may as

well finish it. I eventually managed to do what I wanted. I had to

modify the code for the rvhtmlimport.LoadHtml procedure to save BOTH

Link AND the ts2 (as a comma separate list) into the the

GraphicItem.Tag... then in the OnSaveItemToFile and OnWriteHyperlink

functions I extract either/or/both as need arises.

A FileName property or something in the GraphicItem class would be quite

useful though.
