There will be a few images which will be  in the unidentified section.

This can happen due to BIB#  being not viisible/Missing BIB# etc. Such Unidentified images will be available in a link on each event page. Users can browse through the images and if they find their images they can click on “This is me” button. On doing that the moderator will review your request and will approve/disapprove it. On approval you can login with the same mail id to and you will be able to see your requested images there and you can place the order from there.
