Greetings
I just noticed a problem with the `tag' method:
If I insert an image with
<dtml-var "some_image.tag (border='0', alt='')">
(nice because `width' and `height' are inserted automatically), I get an <img> element with NO `alt' attribute, instead of an `alt' atribute with an empty string as its value (alt="").
An empty `alt' value is important when using images for which it is best not to insert any alternative text in text browsers (decoration-only or redundant image links, for instance), because the absence of the `alt' attribute may not be equivalent to an empty value. In lynx, for example, the file name of the image (more precisely, the last component of the path in the `src' attribute) is shown (yuck) when no `alt' attribute is supplied.
I assume the check for the attribute is only something like that: if alt: ... So an empty string is considered also false. You can work around with <dtml-var "some_image.tag(border='0',alt=' ')"> Since a space is not seen but also not false. HTH Tino Wildenhain
