Hi,
I'm trying to check to see if an image exist. If it doesn't I don't want to display the section. This is what I have. Why doen't it work.

{section show=ne($node.object.data_map.image.content)}
{attribute_view_gui attribute=$node.object.data_map.image image_class=small alignment=right href=$node.url_alias|ezurl}
{/section}

thank you

You are using show=ne(($node.object.data_map.image.content)}

Isn't that the same as saying if there's no image, show the image? Or am I missing something essential here. (It's late and I'm dead tired...)

Anyway here's the "official" method of checking if there's an image. Taken from the "New image system" infopage.

{let content=$node.data_map.image.content}
{section show=$content.is_valid}
    We have an image.
{section-else}
    No image has been uploaded.
{/section}
{/let}

I've used it a lot and it works for me.

best regards
