I am making a j2me application to send an image (taken from a camera) to a PC for further processing. Can I send it over bluetooth using ftp to the pc ?

Probably not FTP, but you'll want to take a look at JSR-82, the Java Bluetooth APIs. Tutorials are available at that site.

While sending files from the pc to any mobile device using bluetooth, the dialog box which shows up mentions FTP. How do I implement the same in J2ME while send files from a mobile device to the pc

I don't know for FTP too, but I used OBEX and avetanaOBEX implementation for transferring files.

If you use JSR-82, you can connect a mobile and PC using Bluetooth and send/receive using input/output streams for the wireless transfer, and link those streams to reading and writing your files.
The J2ME GCF supports Bluetooth using URLs such as btspp:// and btl2cap:// URLs to open connections. There's a good introduction on Bluetooth programming here. Or even better, there's a tutorial on using OBEX for transferring images here.
Bear in mind, to do Bluetooth on a desktop PC (in Java SE), you will need a JSR-82 implementation for the desktop to interface with your Bluetooth chip - you can use something like Bluecove (free) or Avetana (non-free).

Why can't JSR-82 suffice for interacting with the desktop bluetooth chip, just as it does for the mobile bluetooth chip?

The point is that Sun Microsystems does not implement JSR-82 for Java SE, so it's simply not present in the Standard Edition JRE or JDK. JSR-82 in J2ME is implemented only on handsets, where in the Java ME SDK the emulator does not provide any 'real' hardware interface with a desktop Bluetooth chip. That's why you need a third-party implementation such as those I listed above.
