$subdistrict->getDefaultImage($page)

Up: class SubDistrict

This method calculates the most probable image URL on the Library and Archives of Canada web site for the specified page within this SubDistrict. This depends upon the fact that for most enumeration divisions the image URLs are sequential, the first image in the set contains a header page supplied by the microfilm technician plus the first page of the division, and the subsequent images contain two pages. It has one parameter:

parameter	description
$page	The page number of the desired image.

This value is validated that it lies between the minimum and maximum page numbers for the SubDistrict and the case of the pre-Confederation censuses in which sometimes the page numbers increment by 2 each time so that the page number must be odd. If the page number is invalid the method returns an empty string.
