Community/Gallery question

SJLPics

I am a member of the Daily Photos Community, have set a Gallery successfully, have the photos in that gallery sorted to show descending by date. Works great....

Is there a setting that makes the most recently added photo to be the one that shows as a thumbnail in the Recent Galleries page of the Community uploads page? Mine seems to scroll through the photos that are in my gallery kind of randomly.

Here is the Recent Galleries page I refer to:

Here is my Gallery:
http://sjlpics.smugmug.com/Daily-Pictures/Steves-Daily-Photos/12741390_YHHDi#976185622_25apq

Thanks for any assistance.
