[Zope] Re: SVG and smart images

[Ayhan Ergul]

Adobe has a script on their SVG site that detects if a
client has the viewer installed and if not takes it to
the download site. Perhaps, you can start with that
and  based on the existence of viewer you can force
(in javascript) loading of the svg image or the
png/jpeg rendering of it. 

Obviously, if you want on-the-fly generation of
png/jpeg version then you need either something that
can do the conversion from svg or you need to generate
png/jpeg rendering yourself.
