I sell LuLaRoe and all of my inventory photos are on Dropbox. If I want to post a photo from Dropbox, is there a way to do that without first going into Dropbox on my phone and saving it into my Camera Roll? For instance - when I click to add a photo - my option is Camera Roll - is there a way to have Dropbox as an option and select pictures directly from there? I can do it on my laptop, but can't figure it out on my phone!
