The Gallery tool provides six main functions at this time:the following functions:
- Display setup help text when no collections exist.
- Navigate to an image-collection.
- View and edit metadata associated with an image-collection. (deferred)
- View the image-collection as an array of thumbnails.
- Set the sort order of thumbnails based on title.
- View an image full sized, perhaps in a pop-up window.
- View the image-collection sequentially (manual), perhaps in a pop-up window.
- View the image-collecton by playing it (auotmatic).

- Gallery View (and navigation)
- Image View (and sequencing)
transitions are navigation or selection clicks:

There is no way to navigate out of the setup help text. Navigating away to the Resources tool and returning to the Gallery tool may be sufficient to transition to the gallery view. This needs to be verified. |
