Optionally allow nodes to have an image (URL)

[nick]

Some guides may like to allow nodes to have an image, which can then be styled / located as required.

As not all guides will want this, it'll need to be a config setting to decide if it should be shown on the edit page. (Node display will always show the image if set, or a different empty span if not, to help with styling)

How will you decide what the URL to the image will be? I think this needs to be discussed a bit in the context of external image hosting, the possibility of adding image uploads, and special wikiformatting for both.

I suppose your initial plan will be to simply use a URL supplied in a metadata field? How will you impose limits on the width and height of submitted?

I tried to start a discussion about this back in 2004. http://openguides.org/mail/openguides-dev/2004-July/000465.html

(In [843]) Display the node image if there is one, or an empty span if not. (there can't be a node image if node images are disabled). closes #135
