This has been added to the Ubuntu release notes: "When uploading a file to a website, the file browse window doesn't show a preview when an image is selected. This only happens on some websites, when Flash is installed.It appears such websites replace the Nautilus "Browse" dialog with a Flash version (Bug:613886)"
