There are a number of ways you can publish your material to the internet using Opus Creator:
Flash – creates an SWF file which can be included in an HTML file. Whilst you could create a whole website using this option, either as a single file or as a series of SWF files which link to each other, it is not the most efficient..
HTML5 – the is the best option for creating web material as long as visitors have a modern browser which supports the new HTML5 standard.
Plexus Plugin – this provides all the power of Opus across the internet via a browser plugin. However, most browsers now prevent these plugins for security reasons and so Plexus is really only useful for web publications where you are in control of the security settings of the browser. On a company intranet for example, or for a specific customer where the plugin can be installed and allowed.
