Right now I store a cookie with the time() in it. Then, when the user returns i use a if() function to check and see if the post is new. But, it seems to either print all the last post pictures the same, either all new since last visit or all not, depending on if I make take the cookie's stamp and compare it to the post's stamp in < or >. I have my if() in the while() where it prints out each thread, like this board does.
