I want to use one file format for the in-webpage version of an image, but then also provide an uncompressed png download. Does anyone have any web design suggestions on how I can do this transparently and not confuse the user?
@edensgarden I wonder if the styling can be made to look nice without javascript.
@thufie I don't think I've ever done website styling with javascript. Only layout construction from arbitrary json files and url parameters. I've only ever done styling entirely with css and css classes
@thufie hell the only javascript I have for my website (current work in progress) is for the art gallery page. Everything else is static generated using jekyll and markdown and styled in pure css.
@thufie not sure if this is exactly what you're looking for but i usually just put a button explicitly labeled as full quality download on a page as that's pretty clear in my eyes. Other than that I don't know of any other way.
