Store/Present/Share pictures of sites

[steesdale]

Users have an interest to load and present pictures per site. For instance: A user may upload ~3 pictures for the exterior of the site, and have that present as a type of data per site.

We'll work on this on a feature branch feature/image_gallery

Design notes (meeting with @lmatayoshi, @matiasgarciaisaia and @mverzilli)

Field configuration screen

• An "Image Gallery" field can be added to a layer in the "Layers" tab of the Collection management screen.

Upload interaction

• Reuse as much as possible from the CarrierWave::Uploader implementation of the Logo.

Site browsing

• In table mode, display a link that opens a popup and shows the gallery.

Import Wizard

• Attempts to upload that field are ignored.

Download as CSV

• Serializes a Gallery's RESTful URI

Backend

• Create a new "Image Gallery" Field type.
• Create an images table with a uuid field and a blob field.
• The field's config will have an images key that will store an array of image uuid's.
• Check what happens with activities. Add activities for "upload image", "remove image".

API

• An "Image Gallery" field serializes as an array of { uuid, url }. Should work like this both for JSON and RSS formats.
• There are REST endpoints to interact directly with a Gallery field.

Next tasks:

• Create a new "Image Gallery" Field type.
• Create an images table with a uuid field and a blob field.
• Gallery popup (Mata)
• Basic file upload widget (for now support just one image end to end)
• Set up ElasticSearch mappings (check if anything needs to be done)
