This module implements the jQuery Zoom Tour plugin in a Drupal module as a field formatter for field collections. The plugin description from the OP is: Showing a main image initially, we want to be able to zoom into certain parts of the image by clicking on tags, using another image for the closer view. This next step can contain other tags that again allow to show more images. We achieve the “zoom” effect by enlarging the current image and fading in the new one.
Install the module, and use the Features based sub-module zoom_tour_content_type as needed: either an example to create your own field collection or as is. Make sure the Display Zoom Tour formatter is selected on the Content Type Display settings.
The Metis module automates the inclusion of the so called "Metis pixel" (Zählmarke) from the German association VG Wort. The pixel is included as an image that is 1px wide and high and it allows VG Wort to count visits to nodes. Based on that count, VG Wort pays authors royalties obtained through the sale of printers, copiers, and other technical devices that might be used to copy texts.
