I use Flash fxp, its a very easy program to use but its only available for free as a trial. The only limitation is the time you can use ir for. However after the 30 day trial period i just reinstall it. Simple. Once Installed, open it and click quick connect, which is the gold lighting icon above the right hand pane. Then type in the address and your username and password for the site your uploading to. Then click connect and you will see any files you have already uploaded to the site come up in the right hand pane. Then on the left you browse your computer for the file you want to upload, then right click and click transfer and it will begin uploading. Then just wait and your done.
