API & app for sending notifications to iPhone?

In a project I'm working on, I want to send notifications to my user's iPhone from my Chrome extension. The notifications will mostly be about their accounts on my site, and I would like them to be able to reply with the type of action they want taken concerning the alerts.

To help me do this, I found http://pushme.to/₁ which works by allowing the iPhone owner to download their app, create an account via that app, and from then on be able to receive "IM"-like messages and push notifications. I can send my iPhone users messages via http://pushme.to/iphone_users_username by automating that page with javascript. However, it will be imperative that I also send i开发者_StackOverflowmages along with the alerts, and am unable to do that as the site uses a flash uploader.

[EDIT: To clarify - pushme.to has a feature that allows you to send along images with a message, this is what I was referring to]

So, to cut to the chase and hit the bottom line: does anyone know of an app the provides a companion app & API for sending messages that the user can reply to? Meaining that the user receives my messages, can reply to them - and my Chrome Extension receive their replies?

Thanks in advance!

I might be misunderstanding your question, but the push notification framework doesn't support images. You can only send text, badges (the red numbers next to an app icon), or sounds (which must already be installed in the app bundle).

Perhaps you can use a third-party option to do it, but push.me wasn't really designed for automated comms, but for friend to friend IMs. You may have to create your own app to achieve this...I'm not sure of any third party app you could use.
