why would you want to do this? are you going to have 385journalists? you want only the pictures you find apropriate for your site, not any crap out there.
you could do it to have custom avatars, but that will affect performance. if you have 30,000 people it will kill to find 4avatars, while searching for your journalists. isnt that easier to have it in the group of default avatars? where there are only few ids to search through?
i always plan carefully every element of the script, i dont just write it for fun so you endup with your server cooked.
i was really happy yesterday when i removed another JOIN table, so it searches less and it's faster...
as i said before, the script is written the way it is and it will not change to load it more with crap, like other scripts out there.
if you want custom avatars, feel free to make a hack guys.
just dont come and ask me why is slow the page.
