Picture files convert but wont transfer??? Sansa Connect

I want to put some pictures on my new “Connect” using the media converter. I open the media converter and my device is listed with the total memory displayed (but not my external 2GB chip?) I then add my pictures to the converter and edit them and them click “Convert” the file convert but they wont transfer to the device?? I can double click my device in windows explore and it opens 4 folders including a “photo” folder but if i try to just copy pics there is says the device is not connected?! Why wont the files transfer and why wont my extra memory show up???
