How to programatically upload/post an image to an image hosting website without a browser?

I want to write a simple utility to upload images to various free image hosting websites like TinyPic or Imageshack via a right-click context menu for the file.

How can I do this using .NET? I've seen some linux scripts that use cURL to post images to these website but I'm not sure how I could create the post request, complete with an image in C#?

Can someone point me in the right direction?

EDIT:

I've found a pretty good resource. Cropper, a free screenshot tool written in .net, has a lot of open-source plugins. One of them is a SendToTinyPic.. complete with source. Link here:

TinyPic.com doesn't have an API as far as I know, but the Cropper SendToTinyPic Plugin tries to upload using "Screen scraping". The official version of the plugin doesn't work right now, but I put together a patch using the same approach, and submitted it to the cropperplugins project. It's just one source module that changed. Anyone can download the plugins project, and then drop in my patch and it should work.

With the patch, it's PritScrn or Alt-PrntScrn will save the image and upload to tinypic, and stuff the URL of the raw image on your clipboard. All in 2 seconds. easy.

If you don't want the actual tool, you can still look at the source code of my patch to see how to POST a page with form-data and a file upload. No direct link. See http://cropperplugins.codeplex.com/SourceControl/PatchList.aspx and look for #3239.

This example image was produced and then auto-uploaded to tinypic.com with the Alt-PrtScrn key-combo. Example image

To embed it here, I just had to ctrl-V because the URL is stored on the clipboard.

The FlickrNet API makes this extremely easy for working with Flickr from .NET. You have to have a Flickr account as well as an API key and shared secret. Once you have what you need, working with the API is very simple:

// http://www.flickr.com/services/api/misc.api_keys.html
string flickrApiKey = "<api key>";
string flickrApiSharedSecret = "<shared secret>";
string flickrAuthenticationToken = "<authentication token>";

Flickr flickr = new Flickr( flickrApiKey, flickrApiSharedSecret );

flickr.AuthToken = flickrAuthenticationToken;    

foreach ( FileInfo image in new FileInfo[] { 
    new FileInfo( @"C:\image1.jpg" ), 
    new FileInfo( @"C:\image2.jpg" ) } )
{
    string photoId = flickr.UploadPicture(
        image.FullName, image.Name, image.Name, "tag1, tag2" );
}

For ImageShack, take a look to this Application.

Use HttpWebRequest.

Using this class, you can POST data to a remote HTTP address, just set the mime/type to multi-part/form encoded, and post the binary data from the image with the request.
