When I click on Place Yourself On Top Here I am given no option to select the picture I want to be shown. Instead, the system selects ALWAYS the same picture, namely, /hhaokx48ugstpic.html
This is not the picture with the largest number of views, it is not the picture with the largest number of comments, it isn't even the best quality picture (quite blurry in fact). Admittedly, it's close to the top, but not the top.

So, my first question is:
(1) How is the picture selected?

My second question is:
(2) Why am I not allowed to select a picture myself?

Admin, can you please respond?
Thanks.
