Hi,
You are probertly exporting your graphics as jpg, png or gif when you use Xara products for creating graphical elements for the web. Even the export from Xara to HTML will create PNG, GIF or JPG even if browsers support the vector based format SVG. The current status of support for SVG in browsers is that it is not working if you use an Internet Explorer < IE9 or an Android < version 3. (Older versions of firefox or chrome will normally be auto opgraded so in theory they will vanish through time...).

You should read this blog post: http://net.tutsplus.com/tutorials/wh...you-using-svg/ - "Why Aren’t You Using SVG?".

See here an example here: http://screencast.com/t/jepOF7st

Well, I am a happy man and I hope to start using Xara Designer Pro X for generating SVG based graphics, and perhaps Xara should consider adding an option to the export to HTML where you can choose to export graphics as SVG? :-)
