Overview: Media includes both images and documents. To be used on a website the media must first be formatted in a form which the viewer can use.  For images this means gif, jpg and png files  Non-image media can be anything which the person visiting the site can use.  pdf files are the universal document format, but they require special software to change. Warning: Internet Explorer does not support images using the 32 bit print format (CYMK) so the system automatically converts such files to 24bit format (RGB). 

• Text documents and spreadsheets: Use .pdf. Modern word processing and spreadsheet programs (with the exception of products from MicroSoft) can produce pdf files directly.  Word™ files are often unreadable unless both parties have the same version of the program or a copy of Open Office (which may change the formatting). Formatting can also change unless both parties have the same fonts.   For this reason we recommend .pdf files when publishing documents which are to be accessed by the general public. 
• Specialized files: the system will accept animation files (e.g, Flash, Quicktime, and Shockwave) which are fairly universal.  Windows Media files are also supported, if you can guarantee your visitors are only going to be running a windows based system.  In all cases, special plug-ins are usually required.  Note, as of this writing, the Apple iPhone, iTouch and "iPad" do not support Flash as a matter of Steve Job's policy.  A specialized browser is now available which does support Flash on iDevices.
• Galleries: Media Folders can be designated "Gallery" by the user 'Admin' either when created or later.  The system will automatically create a thumbnail version of these files when they are uploaded. 

Please see Add/Remove Media for details on how to add and remove the media from the media libraries.
