Since dadaIMC allows users to upload media files, it needs to know how to display various filetypes in different manners. Supported upload filetypes and their display method are configured in the Mimetypes section.

Maintaining proper mime types is essential to dadaIMC. The software uses extremely strict checks on the mime type and file suffix of uploaded files, to prevent any malicious scripts from being uploaded. Only when a file and its associated mime type match an entry in the mimetypes table will it be displayed on the site.

dadaIMC ships with a default list of supported mimetypes, and a limited number of display methods (image, download, embedded QuickTime, etc). Files uploaded with mime types not specified here are treated as downloadable files, but if you want to add support for new mime types, you can add them here.

The supported display methods are:

Image

Displayed using standard IMG tags

Download

A generic "Downloadable file" icon is displayed, and clicking on it results in the file being downloaded to the users computer

PDF (Download)

A PDF file icon is displayed, and the file is handled by the user's browser — either downloading the PDF, or using a PDF viewing plug-in to display it in the browser

Generic Audio (inline)

Uses a generic OBJECT tag to display the audio, then handled by the user's browser (usually providing an inline control panel to play the audio).

Generic Audio (playlist)

Attempts to play the audio by linking to a playlist file (.m3u)

Shockwave Object

Wraps the media in an OBJECT tag referring specifically to Macromedia's Shockwave codebase, attempting to display it directly on the page

RealVideo (inline)

Wraps the media in an OBJECT tag referring specifically to the RealVideo codebase, attempting to display it directly on the page

RealAudio (inline)

Wraps the media in an OBJECT tag referring specifically to the RealVideo codebase, attempting to play it directly on the page

RealAudio (external)

Links to a ".ram" file that normally causes the file to be downloaded and played in the external RealPlayer

QuickTime (inline)

Wraps the media in an OBJECT tag attempting to load the QuickTime interface directly on the page

WindowsMedia (inline)

Wraps the media in an OBJECT tag attempting to load the Windows Media Player interface directly on the page

Generic Application

First attempts to correctly identify another appropriate MIME type based on suffix, and falls back to a generic "Unknown Media" file that cannot be downloaded (to prevent the spread of viruses and spyware).

Text

Runs the contents of the text file through the cleantext() filter, stripping out potentially dangerous code, and displays it on the page
