Current Photos Of Prancer Will Charging My IPod Nano Delete Any Current Photos I Have On It?

Will charging my iPod Nano delete any current photos I have on it? - current photos of prancer

I have an iPod nano 4 generation, and I invite you to get the music out of it, but I fear it is the photographs that you are there delete them. Just need to know if my photos will remain for the connector for charging, or I must add it again? Please help ...
