Views: Access CCK image delta for each image link
Depending on the views version you use, you have different options to render a multiple values field and the fields themselves.

The easiest thing in this case would be to create a special field formatter for the images. Field formatters are almost exactly same for both Drupal 6 and 7 and is what you could call a theme function for fields. In that theme function you would be able to handle the different deltas, as you will have that variable accessible.
