I need a way for cache images and html files in PhoneGap from my site. I’m planning that users will see site without internet connection like it will be with it. But I see information only about sql data storing, but how can I store images (and use later).
Caching like you might need for simple offline operation is not exactly that easy.
Your first option is the cache manifest. It has some limitations (like the size of the cache) but might work for you since it was designed to do what you want.
Another options is that you can store content on the disk of the device using the file system APIs. This has some drawbacks like security and the fact that you have to load the file from a path / url that is different than you might normally load it from on the web. Check out the hydra plugin for an example of this.
One final option might be to store stuff in localStorage (which has the benefit of being private on all platforms) and then pull it out of there when needed … that means base64’ing all your images tho so that is a pretty big departure from just standard caching.
