I'm sure it's easy, but I'm not seeing it. I have an HTC Incredible. How do I upload files (mainly pictures and videos taken with the camera) to my dropbox folder? I thought there might be a way to go into the dropbox app and upload, but that doesn't seem to just let me upload any file. I also tried copying the files into sdcard/dropbox, but they don't show up in my dropbox account that way either.
