Conditional actions.. we really need them.

I don't think that's a big problem. I've been using the gv_captions module for a while. this module provides a dynamic text action for images. It basically finds out which node a image is attached to and makes the node object available to the action. You can then configure the text by getting info from the node object itself.

This is the code being used to find the actual node:

function gv_caption_image(&$image, $action = array()) {
  // store our variables here
  $caption=array();
  
  // find the image name
  $caption['path'] = substr($image->source, strrpos($image->source, '/') + 1);
  
  // If the image is a cck imagefield,
  // find the image's optional title and alt text, as well as its node
  if (module_exists('imagefield')) {
  
    // a lot of work to find if the content_field_image_cache actually exists yet
    $table_found = false;
    $r = mysql_query("SHOW TABLES");
    while($row = mysql_fetch_array($r)) {
      if($row[0] == 'content_field_image_cache') {
        $table_found = true;
        break;
      }
    }
    if($table_found) {
      // if content_field_image_cache exists,
      // see if we can find info on the current image
      $result = db_fetch_object(db_query("SELECT c.nid, c.field_image_cache_title, c.field_image_cache_alt FROM {content_field_image_cache} c INNER JOIN {files} f ON c.field_image_cache_fid=f.fid WHERE f.filepath = '%s'", $caption['path']));
    }
    if ($result) {
      $caption['title']=$result->field_image_cache_title;
      $caption['alt']=$result->field_image_cache_alt;
      $caption['node']=node_load($result->nid);
    }
  }

However, I don't think we should be doing this in the actions themselves. It would be much better if this could be implemented in imagecache as a default behaviour for all actions. That way we won't have to rewrite every action available to imagecache.

I haven't looked into if this is possible (read: easy) or not but I bet some of you guys know that :)
