Updated to work with Wagtail 2.7 and django 2.2, might not work with earlier versions.
If upgrading:
- Remove the wagtail_simple_gallery from urls and use `WAGTAILIMAGES_INDEX_PAGE_SIZE = 32` setting instead.
v.0.6.4
Added a simple tag feature (12), thanks MorezMartin! Tested with wagtail version to 2.5.1 (Works).
