Default image tpl


I’m trying to customize an image field for my content type, but i can’t find where default image tpl is.

usually for views and blocks i clone the default tpl (for example: views-view.tpl.php) and i modify it renaming and editing the file content, but i can’t find the same file for images field.

in particular what im trying to do is create a custom image field tpl for my content type and printing the image and the alternative text with some container div.

thanks in advance, hoping this is clear.
