* Displays a "displayed gallery" instance

* Alias Properties:

* image_ids/gallery_ids == entity_ids
*
* Default Behavior:
* - if order_by and order_direction are missing, the default settings
* are used from the "Other Options" page. The exception to this is
* when entity_ids are selected, in which the order is custom unless
* specified.
*
* How to use:
*
* To retrieve images from gallery 1 & 3, but exclude images 4 & 6:
* [ngg_images gallery_ids="1,3" exclusions="4,6" display_type="photocrati-nextgen_basic_thumbnails"]
*
* To retrieve images 1 & 2 from gallery 1:
* [ngg_images gallery_ids="1" image_ids="1,2" display_type="photocrati-nextgen_basic_thumbnails"]
*
* To retrieve images matching tags "landscapes" and "wedding shoots":
* [ngg_images tag_ids="landscapes,wedding shoots" display_type="photocrati-nextgen_basic_thumbnails"]
*
* To retrieve galleries from albums 1 & #, but exclude sub-album 1:
* [ngg_images album_ids="1,2" exclusions="a1" display_type="photocrati-nextgen_basic_compact_album"]
*
* To retrieve galleries from albums 1 & 2, but exclude gallery 1:
* [ngg_images album_ids="1,2" exclusions="1" display_type="photocrati-nextgen_basic_compact_album"]
*
* To retrieve image 2, 3, and 5 - independent of what container is used
* [ngg_images image_ids="2,3,5" display_type="photocrati-nextgen_basic_thumbnails"]
*
* To retrieve galleries 3 & 5, custom sorted, in album view
* [ngg_images source="albums" gallery_ids="3,5" display_type="photocrati-nextgen_basic_compact_album"]
*
* To retrieve recent images, sorted by alt/title text
* [ngg_images source="recent" order_by="alttext" display_type="photocrati-nextgen_basic_thumbnails"]
*
* To retrieve random image
* [ngg_images source="random" display_type="photocrati-nextgen_basic_thumbnails"]
*
* To retrieve a single image
* [ngg_images image_ids='8' display_type='photocrati-nextgen_basic_singlepic']
*
* To retrieve a tag cloud
* [ngg_images tagcloud=yes display_type='photocrati-nextgen_basic_tagcloud']
