Galleries are a great way to share images which are often descriptive of events. As events can share themes and there can be more than one gallery in a community, it would be helpful to use tags so that images matching the selected tags could appear in more than gallery without duplicating the original image. For example an image may be tagged with a year or month and also the type of image, e.g. salesevent. Thus it could appear in galleries for the specified year or month and the salesevent gallery with no additional effort.
