Hi, I am new to openseadragon and deep zooming. I want to generate deep zoom tiles for an image of size 50,000 x 50,000 pixels (file size aroung 700MB). I tried using deep zoom composer software but it keeps loading the file without any success. For files uptill 100 MB deep zoom composer works well. Please help me how can i generate deep zoom tiles for such large image. Thanks

@sohaib_ghani_twitter There are a number of tools you can use:
For large images I'm a fan of VIPS

@iangilman The thing is, I don't have a very large image, I have many many small images, let's say one million images of 300x300px each.
If there is a way to load them directly from some sort of index, that would be crazy awesome.

@Lucian_Apetrei_twitter you can certainly do that... that's basically what I do with The problem is one million images means one million trips between the browser and the server, so you really want to find some way to combine them somehow
