I have had many problems with the ActiveX and Java version of this I have had more success with this prototype download the plugin then activate the prototypehttp://static.ak.facebook.com/fbplugin/win32/install/Install_Facebook_Plug-In_1.0.3.exe
There is only one drawback with this uploader you can't rotate the JPEG's prior to import like in the Java Version it is however 100% successfull unlike the default uploader.
Then ACTIVATE the prototype so that when you go to your add photos section it will take over for you when it first runs you will see this window for permission

If you decide to go back to the Java Uploader then you must first DEACTIVATE the prototype on your profile visit the prototype here to do this
