If you have already organized your photos into folders & you want to create an album directly from the photos in those folders, then Dropbox allows you to create one. To do this, Sign In to the Dropbox website & navigate to the folder. Right-click on the folder & select 'Create album' option. Your new album will appear instantly on your Photos page and have the same name as the folder. This album will have all your photos, but photos from sub-folders will not be included automatically to the album.
Note that: Creating albums does not take an additional space in your account, nor does it change the locations of your photo and video files.
You can install PicBackMan's Dropbox uploader for Mac from the website and start backing up photos and videos.
Quick Tip to ensure your Photos never go missing
Photos are precious memories and all of us never want to ever lose them to hard disk crashes or missing drives. PicBackMan is the easiest and simplest way to keep your photos safely backed up in one or more online accounts. Simply download PicBackMan (it's free!), register your account, connect to your online store and tell PicBackMan where your photos are - PicBackMan does the rest, automatically. It bulk uploads all photos and keeps looking for new ones and uploads those too. You don't have to ever touch it.
