The quickest way to see which templates that are used, is to use the "Quick settings" in the right column of the admin-interface. Select "List of used templates", "Inline debugoutput", "DebugOutpu" and click Set.
This will show you the list of templates in the bottom of the debugoutput, and it will also show which template it includes in the source of the HTML.
You should see something like: design/standard/templates/content/datatype/view/ezimage.tpl
