In Chrome, Firefox, Safari, and supported Internet Explorer browsers, drag and drop or select files to upload. Folders of files can also be uploaded if you're using Chrome version 21 or newer.
Files can also be uploaded via a linked Dropbox account. If accounts are linked, a notification stating "Dropbox Enabled!" displays below the upload area.
Files that have already been uploaded to a Smartimage collection can be added to a different collection. To adding files from one collection to another from within a collection, select Add > Add Files > Add Existing from the dropdown. From there, search, filter, and sort to find files from different collections.
