+similar to the float types @code{table} and @code{figure}.  Various options
+exist for placing photos, captions, and a photographer line.  In
+@code{twocolumn} documents, a possibility exists to generate double-column
+floats automatically if the photo does not fit into one column.  Photos do not
+have to be placed as floats, they can also be placed as boxes, with captions
+and photographer line still being available.")
