[TYPO3] captions and links for random images?

[Bing Du]

Hi,

We're using wag_randomimage 1.3.1 on typo3 3.8.1.  When I insert the
plugin, under Images Directory, there is only one Link field.  So the
clickable random images will all go to the same place that the link points
to.  I'm not clear what the Link field is intended for.  But what we want
is for each random image to have its own caption and link.  Is that
possible?

Thanks in advance,

Bing
