Fetching and storing data with App Engine and Python from Android
I am a photographer and new to Android development. I want to create an Android app where a user can choose a picture from a gallery and select a print size. Then when they press Order button - the information (name, address, order info etc) should go to a server.

I want to use App Engine with Python as I was able to pull the guestbook tutorial and it's free.

My questions are-

1. Where or how do I store images in the App Engine that I can easily update like in a folder. Or do I need another website hosting for this?

2. How do I create a file (XML/JSON etc) that will have a picture with information (price per print size, ID, Image URL etc)

3. Upon receipt of a HTTP request, how will I store the information on App Engine on user Orders?

I know it's way too much to ask but I wanna learn and do it by myself. Please don't get pissed. You can give me a step by step links to tutorials which I can follow to avail this.
