Hello, i've added in an image zclass the index_html document. This file is shown, but variables are not working, starting from the <dtml-var id>. Why?

The index_html method of the Image class returns the image data, with the correct Content-Type header.

From lib/python/OFS/Image.py:

def index_html(self, REQUEST, RESPONSE): """ The default view of the contents of a File or Image. Returns the contents of the file or image. Also, sets the Content-Type HTTP header to the objects content type.
