Hi Edward,

A bit of disclosure: I'm one of the developers for Diva.

We have done quite a bit of experimentation for viewing images on various platforms, and even on a Mac Pro with 8GB of RAM and an SSD, 300MB TIFF images still require a bit of waiting for any viewing or operations.

As Dave mentioned, we're developing the Diva viewer to do online viewing. It requires a bit of server setup, but the big advantage is that I find it's actually faster to view large images online in the browser than it is to view them off a hard drive.

These images:

are approximately 170MB for each page (about 80GB for the whole document), but since we only ever serve out the parts of the document that you are looking at, it makes viewing large medieval manuscripts very easy and fast, without sacrificing the ability to zoom in to see very fine details.

We did a bit of testing on the iPad early on, but haven't tested it since we did another round of development.

If you're interested, let me know and I can help you get it set up.

Cheers,
-Andrew
