Patch to create tiles for multiple images in an imagefield

The module currently only deals with the first image of multiple-image fields. Applying this patch to zoomify_imagefield.module should mean that all images are processed instead.

As for displaying them, I didn't alter the theme_zoomify method in zoomify.module as I was overriding it anyway with my own theme function. To do this yourself, the following code might be useful (it switches images according to a URL parameter called 'mediaPage', but you could alter this as you see fit):

function mytheme_zoomify($node, $images) {
  drupal_set_title($node->title);
  $viewer = base_path() . '/' . drupal_get_path('module', 'zoomify') . '/zoomifyViewer.swf';
  $fid_key = $_GET['mediaPage'] ? (int)$_GET['mediaPage']-1 : 0;
  $fids = array_keys($images);
  $fid = $fids[$fid_key];
  $image = file_create_url(_zoomify_filepath($node, $fid));
  $width = variable_get('zoomify_width', 800);
  $height = variable_get('zoomify_height', 600);
  $nid = $node->nid;
  return <<<EOS
<div class="zoomify zoomify-node-$nid zoomify-file-$fid">

EOS;
