Hi @Courtneyluv1013 ,
On mobile devices (including Android phones), files (including photos) don't keep in sync. Once something is successfully upload, you can delete it without affecting already uploaded file. Opposite is true also - you can delete a photo in your Dropbox account (if needed) without affecting the photo in your camera roll.
Good luck.

Yes,.. and so you're going to free up some space for more pics... 😉
