I have been trying to make this work, searched google and here since Friday. My ultimate goal is to be able take multiple pictures with a title and description for each and upload them to a server, then display on a web page.
What I have so far is: the ability to give one image a title and description, browse the gallery, find an image and select it. BUT when I do the image is uploaded along with the form, immediately. I would like to be able to do this using a submit button.
I also have a button to take an image instead, and a preview of the image on the page appears. BUT when I do take an image with the camera I do not know how to upload my form. I was able to print to the screen the image data using a div and innerHTML call... but honestly i'm so lost and do not even know where to start posting specific snippets of code. I will post the entire page as it currently exists right now....

According to this answer: Phonegap android unable to upload image using fileTransfer You cannot use the URI directly....
But, it seems the uri can be used directly... (see my code below)
Edit 25-7-2013 I got this working with: call like this:
navigator.camera.getPicture(onPhotoUriSuccess, onFailCamera, { quality: 50,
destinationType: pictDestinationType.FILE_URI });
and on succes:
function onPhotoUriSuccess(imageUriToUpload){
var url=encodeURI("http://your_url_for_the_post/");
var username='your_user';
var password='your_pwd';
var params = new Object();
params.your_param_name = "something"; //you can send additional info with the file
var options = new FileUploadOptions();
options.fileKey = "the_name_of_the_image_field"; //depends on the api
options.fileName = imageUriToUpload.substr(imageUriToUpload.lastIndexOf('/')+1);
options.mimeType = "image/jpeg";
options.params = params;
options.chunkedMode = true; //this is important to send both data and files
var headers={'Authorization':"Basic " + Base64.encode(username + ":" + password)};
options.headers = headers;
var ft = new FileTransfer();
ft.upload(imageUriToUpload, url, succesFileTransfer, errorFileTransfer, options);
}
By the way, I use an apache webserver on the api site, I saw here, nginx could have a problem with the chunked mode: PhoneGap chunckedMode true upload error
