Re: Displaying images for html output

Image Extension
===============

Thusly, @image must use ".png", also for html output to get the following to 
work

@image{../../Ideogr/Ch03b--Chmed/igc03--01--Sicl--CircAmRg,8cm,8cm,AltText,.png}

File Location
=============

Regarding splitting the file location to use @value

E.g.

From
@image{../../Ideogr/Ch03b--Chmed/igc03--01--Sicl--CircAmRg,8cm,8cm,AltText,.png}

To

@set imgpath ../Ideogr/Ch03b--Chmed
@set imgname igc03--01--Sicl--CircAmRg
@image{@value{imgpath}/igc03--01--Sicl--CircAmRg,8cm,8cm,AltText,.png}
@image{@value{imgpath}/@value{imgname},8cm,8cm,AltText,.png}

This works for html output, but not for pdf.

Could these two things (File Extension, @value in file location)
be added to the TODO list for Texinfo?

Christopher
