andfinallyI've modified Henrik's very handy plugin to add some extra features. On upload the plugin now
- Saves some metadata about the file uploaded. The data's saved in a text file which has the name of the uploaded file + ".txt".
- Leaves a copy of the uploaded file and metadata text file in the temp directory.
- Copies both files to Dropbox.
- Emails a notification about the upload.
The code below should replace the contents of Henrik's main plugin page wp-dropbox.php. Hope someone finds this useful!
