Drew McLellan 04 December 2011 Sripathi – I think the REST point is an important one, and a concern I share. Each unique image file should have a unique URI, so it would be ideal if a new URL could be generated client-side before the request is made. I’m not sure the sub-domain for mobile, another for tablets really works, as what size is a mobile or tablet screen? Most single devices have two sizes at least. Would seem more appropriate to include the breakpoint size, if anything. Sort out the REST issue and the CDN issue sorts itself. The whole adaptive images issue is a difficult problem that’s not yet solved, so the more discussion and sharing of ideas the better.
