Anyone have any ideas on a upload progress bar???

Thanks in advance for anyone's replies to my question yesterday. I now have another question, is it possible to implement a meter that would display the upload progress of said upload (one sent via the POST method)? I would like to add such functionality to my little file drop box I'm putting together. At the very least, I would need a popup window that displays a message like "Your file is now uploading" followed by an animated gif of a file copying or something to that effect. This window would then need to automatically close upon successful file upload though. I thank you all in advance for any replies or suggestions you can give me in this matter. -- Tim Meader ACS GSG tmeader@cne-odin.gsfc.nasa.gov
