Bummer, the images display not at all with JavaScript turned off and there's no way to link to a specific image. Degrade gracefully y'all.
That's not his responsibilty at all. Try contributing to an open source project instead of complaining.
It's very easy to handle a Javascript fallback for Slider.js: Instead of having an empty container in which your slider will be templated, put the content for the non-javascript into it.
That's it ;) Just because the Slider Javascript will empty the content of it ;)
(Side thought: maybe I'm wrong, but in 2011, are we still need a JS backwards?)
1) Your website requires backwards compatibility
2) It's not his problem
Better whine and complain on the internet until someone fixes your problems for you.
