How to add assets to an existing album in the FotoWeb Pro interface.
Adding files to an existing album
Having selected a number of files you want to add to an album (you may have selected them in the grid, added them to the Pins bar or isolated them on a separate tab) you can drag those assets into the album in the right side panel.
Tip: You can open an album as a tab in FotoWeb Pro by clicking its title in the albums list.
Then it's possible to select files in an archive on a separate tab and dragging and dropping those files to the album tab to add them to the album. You'll see the album update in the right side panel as well the second you add files this way.
