The gallery page is an individual page. If you would like to have multiple static versions of this page then you would need to add them to the contents with SiteSculptor. This however would require to you recreate the site.
I think it would be best to make the page a dynamic one based on a recordset, this way you could make use of the single page for many images. To do this you would need a table in your db with the information about the images including the file name. If the images are all in the same directory then you do not need to record this info. You could then add a recordset for this table to the page and use the repeat region to have it show one record at a time.
