Add zooming capabilities to question list image

[aruizca]

We will also add a responsive gallery with all images

Is it possible to use the existing image zoom capability instead of adding a new one ?

What we've added on dev is very slow from here - presumably because it is loading the whole image instead of using the tiling capability

You are right. Outside CSIRO some images take too much time. I think the problem is that I am using the original image instead of a thumbnail which is probably enough.

I guess the name of the task is misleading here as it is not really zooming tool cause you cannot really zoom in to see details. It is just a component to show a gallery of the available images in a more practical size (at the moment is requesting the original image) without cluttering the UI. I think the aim of the zoom viewer with tiled images is more about being able to see the details by zooming in and also to improve load times.

Regardless of all that I think I could try and create a gallery component reusing the leaflet viewer and make it similar to how it looks in the details screen but on a floating layer. Please confirm.

sounds good.

i've sent you messages on HipChat on this. We have a need for a generic capability to support viewing multiple images for multiple apps - see AtlasOfLivingAustralia/specimenbrowser#10

I think we should do this just in javascript (extending ala-image-viewer.js in the images-client-plugin) using the leaflet with leaflet controls for 2 reasons:

• support switching between images in full screen mode. If its done with leaflet controls, nice things happen. See http://timeseries.ala.org.au/ and hit full screen.
• the existing tools in images-client-plugin (subimaging, downloads, info, scaling) are
  written in this way

this will also be something we reuse on the identification page..
