On the gallery uploading page, select Dropbox. If it's the first time, this will prompt to enter the username and password for the Dropbox account you wish to use.
After logging in, select “Choose from Dropbox” to access the Dropbox account. Now select the files or folder you wish to upload to the current gallery. There is no limit on the amount of files uploaded at one time, but users can only upload from one Dropbox folder at a time.
Once the files are selected, click “Choose” in the bottom right corner. All of the content selected will begin uploading into the gallery instantly. If needed, follow the steps again to access content from various folders.
What Happens Next
When content is added in the queue, it will begin downloading in the gallery. Depending on the size and number of content this may take several minutes. However, you may exit out of the queue while you wait and begin tagging ambassadors while content is uploading.
