Snippet: PHP Snippet Fetching ezimage datatype image alias properties
Introduction
Did you know that you can use the eZ Publish kernel api to obtain image alias properties from content object attributes which use the ezimage datatype.
Example
This is a simple php example of how you may use the eZ Publish kernel api to obtain image alias properties. This example comes from a simple example custom module view.
