How to import stuff on a SD card using a camera

Hi, I import my videos and pictures on my PC thorugh the camera but I want to add stuff and it won't allow me thorught the camera. Is there a program where you can use your camera as an SD card reader (or at least allow me to access, insert stuff into it)?

no. Its entirely dependent on whether or not the camera allows it.

Just use a card reader for the sd card.

Well, some cameras have bluetooth option or a cable-to usb.... but mostly, a sd card reader is the best cause it wont use the camera's batteries.

I don't have a card reader and I really don;t care about the battery life either. I just want to like load pics and load stuff onto the SD card. As in use the Camera as an SD card reader if possible.
