there are three questions:

1: how to upload and store a image on a webserver
2: how to send an image to the webserver
3: how to trigger uploading an image with respect to network-reachablity

1: Restful-Service or normal web-form-file-upload

2: depends on the method you choose in 1. if restful-service: binary-data in HTTP-Body; if web-form-file-upload via multipart then take a look at this so-thread

3: either just try sending: you will get an error if the iphone is not able to send data and thn try a few minutes later. Or use the Reachability-Example from Apple which is able to notify you about internet-reachability.
