While you're probably referring to archival/dc images where the resources already suggested probably make more sense, for general web images--which can also be big--it's time to start using the <picture> HTML element and the picturefill polyfill for unsupported browsers. Support tl;dr: The <picture> element is currently under consideration for IE. It will be supported in Firefox 33 and Chrome 38. Picture element: http://www.whatwg.org/specs/web-apps/current-work/multipage/embedded-content.html#the-picture-element Picturefill: http://scottjehl.github.io/picturefill/ Currents support landscape for <picture>: http://caniuse.com/#search=picture IE Platform Status: http://status.modern.ie/pictureelement?term=picture -----Original Message----- From: Code for Libraries [mailto:[log in to unmask]] On Behalf Of Jon Stroop Sent: Friday, July 25, 2014 12:10 PM To: [log in to unmask] Subject: Re: [CODE4LIB] very large image display? Jonathan, We use an image server I wrote, Loris, plus OpenSeadragon. Here's an example: http://libimages.princeton.edu/osd-demo/?feedme=pudl0123%2F8172070%2F01%2F00000001.jp2 That image is 152500 x 4000 px: http://libimages.princeton.edu/loris/pudl0123%2F8172070%2F01%2F00000001.jp2/info.json Loris is on Github: https://github.com/pulibrary/loris as is OpenSeadragon: https://github.com/openseadragon/openseadragon More generally, this is one of many problems IIIF (International Image Interoperability Framework) exists to try to solve.
