Is there anyway to just get the date that the last image was uploaded? I would like to include a link on my main page that says Images last uploaded x/xx/xxxx, and then a link to the latest uploads. Any info would be greatly appreciated.
Run a mysql query to get the ctime of the pic with the highest pid.
SELECT ctime FROM prefix_pictures ORDER BY pid DESC LIMIT 1
That will give you the unix timestamp for the latest addition which you can format as you like using date().
