Uploading image to a webserver

Sure,
The first thing you will need is somewhere on the web to store the image. Easiest thing to do here is go out and purchase a web hosting account from a provider such as Bluehost or HostGator, etc...

Next, you will need to create a servlet to run on the server and receive the image file from the client and place it on the server. For this, you can use Java, Python, etc...

Lastly, you will need to use the DefaultHttpClient class to connect to your servlet and send the image data via an outputstream.

Another option if you don't necessarily like or know how to work with servlets is to use a 3rd Party FTP library to upload the image via FTP.

 

& a minor detail though to add to @jonbonazza's point, with http i.e DefaultHttpClient or UrlConnection or any other HTTP protocol you'll have to use multi-part form data to upload the file. As an alternative you can use sockets to just send it as binary stream, but if your users are behind firewall, proxy etc. ports other than 80 (HTTP) are most likely blocked.

 

Always go small [least resistance route] first to test your theory

 

Congratulations

& trust me I understand multi-part form data with UrlConnection on 2.1 device -- i've known it first hand if something goes wrong in future pay special attention to headers you're sending across and exact spacing, naming of multi-part fields

Good luck to you on your app
