I have just setup a webcam with the yawcam software. It is creating a file series called image00.jpg - image96.jpg. As indicated in yawcam dox, image00.jpg is always the newest file created, which is perfect.

Now on to the Cumulus problem..
I have configured Cumulus to upload only a single file: c:\cumulus\webcam\image00.jpg (created by yawcam)
Other options ticked are: binary? and FTP?. No other files are to be uploaded, so the include standard files/images, solar/uv/sunshine options are UN-checked.
FTP logging is on. The session is established, but it appears no attempt is made to upload a file. (The file does exist!) No ftp errors are encountered. The ftp popup window shows a logging in and a logging off entry.
Any suggestions?
Here is part of my log:
