Another option to create openseadragon compatible files is Microsofts Deepzoom Composer:

It's probably not a great option for lots of files, but it's a pretty good gui based option for smaller projects that also creates an html page with the required javascript files to create a zoomable web page off the shelf that you can customize to your liking. I haven't used it in a couple of years so...

If you store the images in JPEG2000, you can pull tiles or different resolutions out via JPIP (JPEG 2000 Interactive Protocol)

Unfortunately, most web browsers don't support JPIP directly, so you have to set up a proxy for it.

For an example, see Helioviewer:

Documentation and links to their JPIP server are available at:
