The picture properties screen allows you to view (and change) properties about a single picture. If you have multiple pictures selected when you use the Picture Properties function, the Multiple Picture Properties screen will be displayed instead. The Picture Properties screen has multiple pages that show different aspects of the picture.
Caption: This allows you to set the caption for the picture. This caption is displayed on the FotoTime website (as a tooltip and on the picture detail screen). While captions are very useful, they are not required.
Keywords: You can assign keywords to your pictures that allows you to quickly search for pictures with those words. The keywords do not get displayed anywhere, so they are useful way to categorize pictures without creating "artificial" or hard to understand captions. It is easy to add or remove keywords to multiple pictures using the multiple picture properties screen.
Picture Date: The date the picture was taken. The picture date is automatically supplied from many digital cameras (using embedded EXIF data). FotoAlbum supports many date formats including partial dates (if you only know the year or month it was taken). This field is optional, but if a date is not entered, you will not be able to use the advanced date filtering. This field is displayed on the FotoTime website on the picture detail screen. You can click on the calendar button to display a calendar for easy selection of a date.
Picture Time: The time the picture was taken. This field is optional but can not be specified without also specifying a date.
