I'm trying to download a PNG icon ("7Zip") for ObjectDock. When I click on the download link (using firefox), rather than starting the download, a web page opens with the actual image shown. If I right-click on it and select "save image as" it creates a file named "download.aspx". If I try in download in IE7, again a page opens with the image displayed but this time it's associated with some sort of QuickTime Plugin. Can anyone explain what's happening?
