Someone was asking me how to upload numerous images into Facebook the other day, hence I decided to give it a try. I was trying out Batching using the 'GraphAPI_Web_1_8_1.swc' Library but it seems to be broken for uploading a series of images. Hence, I have created a simple workaround for uploading multiple images.
Android Services is something that is pretty much similar to your windows background services. It is something that will be running in the background that requires an minimal amount of memory usage. The following would be a simple demo that I had created to help you to understand it better.

* Click here for the demo.In the past, if you want to create a flash site that allows user to upload their own image, you probably would need to upload the image to a server and retrieve it back after uploading. This can be quite lame. But in Flash Player 10 onwards, you can throw the step of connecting to a server away and attract the file you have uploaded immediately.

Despite with all the new web technologies around us, I guess that XML is something that wouldn't die out so easily. Especially that its a friendly file type that can be opened by different browsers and softwares. Ex: Mozilla Firefox, Google Chrome, Microsoft Excel, etc... Therefore I'm going to share an example using php that would display the results as a xml data.
<?php
//Header needed to display content as xml
header ("Content-Type:text/xml");
//function to create xml node
//if $hasIllegalCharacters is true, then we will use CDATA to wrap the node values
function createNode($nameOfNode, $valueOfNode, $hasIllegalCharacters=true)
{
$result = "";
$result .= "<" . $nameOfNode . ">";
if($hasIllegalCharacters)
{
$result .= "<![CDATA[";
}
$result .= $valueOfNode;
if($hasIllegalCharacters)
{
$result .= "]]>";
}
$result .= "</" . $nameOfNode . ">";
