How do you export a folio for users to download on the web and view in their browser?
Martha Stewart did this with her first digital publication (https://bb.marthastewart.com/MSL/February/4.php)...
I have no access to it but I’m sure it was a lot of work.
So there is no way to export a folio from inDesign that users can download and view on their computer?
...and have no estimate of when it will be possible?
It’s been discussed. That’s all I know.
I know that the designers at Martha Stewart Living worked directly with people from Adobe when they published their first digital magazine. That link you're pointing to was something they did custom with Adobe.
