Using The Twitter API
Using the Twitter for iPhone API is fairly straightforward. Open up you Twitter iPhone application and navigate to the Settings. Within the settings, locate your Image Services configuration:
Accounts » Settings » Services » Image Services
Here, you will be presented with a list of pre-configured services as well as the option to provide your own Custom API end-point:
From this screen, select the "Custom..." option. This will provide you with a place to put your own custom uploader API end-point:
In this input box, enter: http://pict.tw/api/upload.cfm and hit Save.
That's all you have to do. At this point, your Twitter for iPhone app will start using the "Show Me Your Tweets" upload service, returning a short-url for the uploaded image.
