I am writing an iphone stylye website and am putting some wallpapers available for download on it. however i am struggling to make a download link the will actually DOWNLOAD not just display the image in the web browser. Even mega upload doesn't work!

So could someone post a guide or some html to get an image download on the iphone?

An if possible is there any way of making the download go into the saved photos gallerey on your iphone?

Here's my site, I've only just started so it isn't very big yet.
