ImageFlow is a picture gallery which allows an intuitive handling of images. The basic idea is to digitally animate thumbing through a physical image stack. That intuitive handling is automatically caused by the metaphorical use of the well known process of thumbing through.

This solution is known as the Cover Flow technique, which has been developed by the artist Andrew Coulter Enright. Now - after it has been bought by Apple - it is used in iTunes and the file browser of Apples OSX.

ImageFlow for Joomla was derived from ImageFlow 0.9 by Finn Rudolph.


  • Supports multiple instances of the gallery on a single page.
  • Thumbnails, with reflections, are automatically created from the source image and cached on the server for quick retrieval.
  • Blurring, darkening or grayscale effects can be applied to non-focused (not the center) thumbnails to make the focused (center) thumbnail standout. (PHP 5 required).
  • Cached thumbnail size is specified as a percentage of the source image size.
  • Images are loaded via an image list text file, all images in a single directory or both.
  • JPG, PNG and GIF image types are supported.
  • When loading JPG images from a directory, IPTC and/or EXIF metadata can be used as caption information for image popups.
  • Auto-step mode can be used to automatically rotate through the thumbnails at a specified interval.
  • Thumbnail reflections can be created with or without transparency.
  • An upper limit can be set on the number of images loaded from a directory.
  • Optionally hide or show the image slider, caption line and navigation buttons.
  • Scales 100% dynamically. The look and size of the imageflow container can be easily modified via CSS.
  • HTML output of the images is controlled by an output template file that you can create. This means that ImageFlow can be adapted to any one of several image popup display scripts (Shadowbox, Lightbox, Highslide JS, etc.). A number of output templates are provided including templates for Shadowbox, Lightbox and Highslide JS. By default, Highslide JS is used to display the popup image. Note: Highslide JS must be installed seperately. It is not installed by this module.
  • When using the image list file option, the default output template can be overridden for any image in the gallery. This allows you to have url links and image popup thumbnails all in the same gallery.
  • Mouse wheel support
  • Arrow key support
  • Loading bar


The thumbnail generation functions use the GD image library. Transparent reflections require version 2.0.1 or greater. You can check the PHP configuration of your site by logging on to your administrative backend. Click on the Help/System Info menu item.



From there, select the PHP Information tab.




Scroll down the page and look for a section that resembles the one show below. If you can't find the GD section or the GD version does not meet the criteria above, you will need to upgrade your PHP configration to use this module.
