Introduction
============
Adds a "Image tags" layout view in Collage to display object images 
tagged with `collective.imagetags <http://pypi.python.org/pypi/collective.imagetags>`_.

Layouts are registered only for objects providing the following interfaces:

* Products.ATContentTypes.interfaces.IATImage
* Products.ATContentTypes.interfaces.IATNewsItem

A special "Settings" viewlet is added in the Collage viewlet manager to
set the scale to use to show the tagged image.

Extending
=========
To provide this layout to your custom content types just copy the 
code below (as stated in ``browser/configure.zcml``)::

    <browser:page
        name="tags"
        for="<your_interface_here>"
        permission="zope.Public"
        class="collective.collage.imagetags.browser.views.ImageTagsView"
        layer="Products.Collage.interfaces.ICollageBrowserLayer"
        />

If you want to use a special template, add a template ``attribute``. 
If not, a default template will be used from ``browser.views.ImageTagsView``.

Features
========
- i18n support (English and Spanish translations)
- Tested in Plone 4.0b5 with Collage 1.3.0_b4
- Settings viewlet displays an inline ``z3c.form`` to set preferences for the layout (available image scales for current object)
- Depends on ``Product.Collage`` and ``collective.imagetags``. They will automatically fetched during buildout and installed during installation of this product.
