I want to add a module to lyxconvert_221.py to change this: \begin_inset External RasterImage,"taulogo.png",""
\end_inset to this \begin_inset External template RasterImage filename taulogo.png \end_inset throwing away the final arg (here "", more generally "<string>") that holds the parameters variable. I guess that we could retain the filename within quotes as LyXLeX will handle that. Trouble is, I don't know how to split the line into its constituent parts. Could someone write the 5 lines of code? Pleeeease? -- Angus
