Is it possible to ensure the apple-touch-precomposed-icon is preloaded before being added to the homescreen? Currently, when tapping "Add to Home Screen" from Safari, a screenshot of the page is used until the icon is downloaded. This seems to be done to conserve bandwidth during page load.
I attempted to include the icon as an img
on the page hoping it would be cached, but that approach didn't prove effective. Are there any other suggestions?
