I do not have an add pictures or mini browser option on my gallery and yet they are at the top of my "page views" stats when I check my host stats page. also displayimage.php keeps coming up top and yet if I click on it it comes up with an error message, why are these page viewed/rerquested, is it something a search engine is doing while trying to find pages or are peolpe trying to find ways of hacking/adding stuff to my gallery. Others pages hit on are mydirectory-albmgr.php and delete.php is someone looking for a loop in the security of my site ??
You would need to look at your site logs for details. For example, check the IP address and see if it matches your own.
displayimage.php is the intermediate pic page. It is bound to be popular. You can't call it without providing parameters.
