Loading a large gallery

[devamchakrabarty]

Hi, when we try to load the viewer with 100 or more images, we have noticed

• the first image waits for quite a while before being shown. We think it waits until all 100 GET requests to the server have completed.
• clicking a thumbnail sends 2 GET requests to the server but the thumbnail image is not refreshed with the latest image returned by the server.
• If we call update on the viewer it refreshes all the images in the gallery and therefore takes quite some time again.

So, our requests / questions are

• Is there an efficient way of lazy loading many images in a gallery?
• Can the first image be shown immediately while the other images are still loading?
• Can the thumbnails be refreshed without having to re-render the entire viewer?

The Viewer.js may not be a good solution for a big list of images currently. A lot of improvements should be done in this case.
