Stuck with that flickr weather one...
I got the url of images from the server (something like : http://example.com/image.jpg). Now i have to download and display them in an image control. But the code for downloading "downloadfile()" is not working. So is there another way of downloading or displaying them?

This seems to work, does it help ? (credit to KJags for similar post ;) )

var url = "http://blog.marketing.ai/wp-content/uploads/2013/04/Link.jpg"; // whatever your url is to the image.
var file = WidgetPath+"Link.jpg"; // save location and file name

function button1OnClick(Sender)
{
DownloadFile(url,file, "UpdateImage"); // run function after download
}

function UpdateImage()
{
image1.Src = "";
image1.Src = file; // update the image
}

Thanks meme... Looks like it will do the job. But isn't there any way to know whether the file was successfully downloaded?

Maybe, delete the file with
DeletFilesToRecycle(file,0);

then download the file
DownloadFile(url,file, "UpdateImage");

then in function UpdateImage() (because this seems to execute after the download is complete) check if the file exists with
FileExists(file);

If the file exists the download was successful.
