See Nook Tablet Support: Frequently Asked Questions, Beyond eBooks, FAQ#8: How do I transfer photos, music, and other personal files onto my NOOK?
That doesn't answer the question of how to transfer pictures and things from the Nook itself to the SD card. The FAQ only answers how to transfer things from your computer to your Nook.
It's been awhile since I've played around with the NT, but I don't believe you can transfer directly from the NT's internal memory to the SD card. It may be possible through a third party app, but I don't know what app available in the Nook Store would be able to do it.
Open Explorer is a free app that should work. It will you to move files you have downloaded from the nook on-board memory to the sd card. You wont be able to see the "hidden" partition (ie books and such downloaded directly from the B&N store.) Also pay attention to what the drives are called - believe the on board memory is called mnt/sd_card and the "real"sd card is called mnt/ext_sd_card (or something like that.) There may be other apps that will work.(QuickOffice used to have that ability a long time ago, but wouldnt purchase it just for that reason.)
