Show an image.
  • src image source (can be a relation, default = ‘self’)
  • link transform image into link (target evaluated as RubyLess)
  • mode size of the image
  • alt_src alternate source to use if src is not an image
see zena 1.0

Display an “img” tag to show the current node.

Simplest example:

<r:img/>

Display an image with a different mode:

<r:img mode='pv'/>

Use the image in ‘preview’ mode to link to full object:

<r:img src='icon' link='this'/>

And finally, use an alternate source in case the current node (this) is not an image (alt_src is either RubyLess or a query):

<r:img alt_src='icon' mode='std'/>

The “icon” alternative source is a special keyword that is translated to the following SQLiss image or icon group by id,l_id order by l_id desc, position asc. This means that it will try to find the linked icon or it will use the first image in the object.
