Ch.7 Downloadables and Plug-ins
The plug-ins are not just applications that help the browser do a job, they are chunks of code that, effectively, makes themselves part of the browser.
Plug-ins extend the browser's capabilities to view and interact with non-traditional, sometimes new file formats not directly supported by browsers. This category includes most of the available multimedia that you might consider using on your pages.
A plug-in is a dynamic application associated with a specific platform and browser. A plug-ins primary purpose is to extend the functionality of the browser by providing efficient, seamless integration of multimedia formats.
Plug-ins include:
- Acrobat Reader for .pdf-files
- Flash/Shockwave for .swf-files
- RealPlayer for .ram-files
Plug-ins can be installed:
- Online
The plug-in is dowloaded and installed on the client - Offline
The plug-in is installed from a CD-ROM or from the hard-disk. - Pre-installation
Some of the more common plug-ins are pre-installed by browser manufacturers, for example Shockwave and Flash players.
To create a downloadable file, you must link to a filetype that is not natively supported by the browser of its plug-ins.
When you provide a link to a downloadable file , you should also provide two more pieces of information:
- the file type the user are going to download
- the file size so users will know how long it will take to download
When you are using technologies that require a plug-in, be sure to include a link to where they can download the plug-in should they not have it installed.
