[TYPO3-english] add link to multiple image captions

[Muriel le Pair]

Hi,

If the image_link is set I would like to display it as well in the 
caption. The image content element can contain multiple images.

This example https://typo3.org/documentation/snippets/sd/255/ is not 
working in TYPO3 6.1.7 so I played around a little and tried to do the 
following:

tt_content.image.20.caption.1.stdWrap {
   typolink.parameter {
     field = image_link
     listNum.stdWrap.data = register:IMAGE_NUM_CURRENT
   }
}

This will display a link in the first caption, all others are ignored.
What am I doing wrong?
