When I started developing File & Image Uploader, I didn't know too much about how to make it. Since that time I have learnd many things and I realized, that libraries from Microsoft are really bad (some user experienced "superspeed", many timeouts, bad proxy support, no speed regulation etc.).
Not long time ago I found great libraries and they are great I think. They have much more functions, less bugs and are cross-platform (can run on Linux, MacOS ...). Just my uploader is done for windows (so it won't be that portable). But I hope it will be possible to run it in Wine (in Linux).
So, there it is. You can try it and let me know, if "bad" things disappeared.
I hope that people who had any problem with File Uploader will now try this out and report if this is better
