Subject: feature 280: Allow visitors/users to choose image ordering inside a
 category

improvement 82: Viewing pictures from remote galleries does not check anymore
for the high pictures (existence flag added to create_listing_file and db)

correction: link element in picture is in the head instead of body (w3c spec)

correction: in profile.php the current template was not selected by default
