There are plenty Drupal modules that offer ways to upload new files and to attach them to nodes. There's the core upload module, the image module that creates an image content type, filefield that creates a CCK field, ... The options are much more limited when it comes to re-using already uploaded files. You could use a nodereference field or image_attach to link image nodes, or a WYSIWYG plug-in like IMCE, or the WebFM module, and that about covers it.

For a current project in Drupal 6 I was looking for a CCK widget that allowed me to upload new files as well as easily access existing files. Drupal 5 has the asset module and Drupal 7 will have the wonderful media module but for Drupal 6 the options are very limited. After a lot of searching I came across the FileField Sources module. It enhances the filefield module (that allows you to upload new files) by adding a way to import files by url and by adding an autocomplete field to search for existing files. One of its most interesting features for me was the bridge with IMCE. All in all these three extra options allow for an incredible flexibility in file management. And because the selected file eventually ends up in a filefield field it can be plugged into the multitude of modules that support it, such as media mover for instance.

I posted a book review on the CivicActions blog about Aaron Winborn's Drupal Multimedia. Follow the "Continue reading" link to see the complete post.

In Drupal Multimedia Aaron Winborn covers media handling in Drupal and provides information on how to embed and manipulate images, audio and video. Packt Publishing provides a dedicated page which lists the complete table of contents and where you can download all example code used in the book as well as a sample chapter.

The first chapter provides an in-depth introduction to Drupal, covering nodes, regions, blocks, themes and modules in general and cck and views specifically. The advanced theming section contains information about custom regions, hooking into template.php and creating template files. Each topic comes with clean example code, plenty of comprehensive screenshots of the different configuration forms and of what the end result looks like and notes with extra clarifications, tips and tricks. The author does a great job in describing the basic Drupal concepts, making this chapter really useful for new Drupal users.

I posted an article on the CivicActions blog about posting recorded videos as comments. Follow the "Continue reading" link to see the complete post.

More and more web publishing platforms are starting to integrate video comments. YouTube and TechCrunch use them and embedded commenting systems like Disqus make it really easy to enable them on your site. Drupal has its own ways to provide integrated video comments, although most solutions are currently only available for Drupal 5.

The asset module was created by Roger Lopez as a means to handle all types of files without needing to install imagefield, audio, youtube_cck, imce and a couple of other modules. An asset is any type of file that has been uploaded in the asset wizard: images, audio, youtube videos, flash movies, text documents, pdfs,... Permissions can be set to both assets and directories, making them publicly available to anyone, to specific roles or just to yourself. For the new drupal-powered amnesty.org the Amnesty International team needed such functionality, and much more. So for months the asset module has been updated, improved, tweaked and made more user-friendly. All these changes have now been contributed:

• CCK field, with instantaneous in-line preview
• Support for panels to create galleries and a preview block that links to these galleries, in the asset_panels module
• Support for .flv files in the asset_bonus module
• Upload a bunch of files with ftp and import them all with just one click using the asset_import module
• Ability to edit/move/delete assets and folders and to change their permissions
• Lightbox support
• Improved imagecache support
• Improved TinyMCE support
• Better i18n and mullti-site support
• Many GUI improvements

With these changes, the asset module integrates with the 3 most used modules (cck, panels and views) making it very easy to implement and integrate with your current site. Roger Lopez has been making a lot of changes himself in a separate version (currently not committed yet) so I hope to implement these changes as well, such as the use of thickbox instead of a pop-up for the asset wizard.
