Dropbox is awesome for storage of images, PDFS, videos and more. Sign in to your Dropbox account via Wecora and you can add multiple images at once.

To do this, click the orange + from any Wecora board, then select DROPBOX. You'll be prompted to login from there. Once the account is in sync, you'll click the orange +, DROPBOX, and your items will be there for your access.
