      The filelist can be defined by one or more glob patterns.
      It is recommended to use a variable with a default pattern 
      as value for the 'glob' parameter. 
      #>
      <@ filelist { 
        glob: @{ files | def('/shared/image-*.png') },
        sort: 'asc'

      <# 
      The 'foreach' statement initiates an iteration over all files in the filelist.
      Note that it is possible to define resize options within the statement to be applied 
      to the files.
      To access a single image it is also possible to use the 'with' statement.

                A caption can be saved along with an image. To get the caption for
