i tried uploading my first four pics in the java window. after a few seconds i get the "technical error" tiny window :-S without any managed upload. could you tell me why this happens and how i can fix it?
Try to update your java to most current. Also be sure that you have as few programs/processes running as possible so your not taxing your RAM too much. Try to have only one browser open at a time and minimize the number of open tabs (that means closeing facebook). If none of that helps try the FTP as Igor suggested.
FTP is file transfer protocol...it is basically a piece of software that will allow you to connect to the DT server and upload your files. Google a program called FileZilla...that's what I use and it's incredibly fast!
