I have an image-heavy web page that needs to be viewable offline on mobile devices.
I found a jquery plugin/tutorial do store images in local storage, but that won't work for my purposes.
Is this something that can easily be adapted to use indexeddb instead?
Also, my images will be updated periodically. Is there a way I can automatically clear the cached versions after a certain amount of time, and force the user to re-load from the web?
