This may seem like a stupid question, but have you installed the drivers for your SD card reader and have you verified good working condition in the Divice Manager?
I can view pictures on camera but when I am inserting it in PC through card reader it is showing blank.
have you tried to view them using the usb connection between camera and pc using a compatible software? It will prove that the chip is capable of being recognized by a PC..may be a compatibility issue between your reader and the chip...
