If I delete my pictures off my iPhone, will it delete my pictures on Dropbox as well?

I'm going on a trip overseas and really want to empty out my Camera Roll Pictures off my phone before I leave. I don't own a Macbook so I have to use Dropbox in order to move all my photos to my PC. I really want to empty out my pictures and i'm afraid that I will loose everything on Dropbox if I delete my pictures on my Camera Roll.

No! It will keep all your photos just fine… DropBox is online so they will be there. You can even set up automatic uploads and then delete the photos off your phone.

Yes it will. Move them into another folder before you clear your phone.
