I know about these. that's why I mentioned them. my problem, as I stated,
is that when I use them in an inline image generator to randomly select an
image from a database, I get the same images on the page. I refresh, I get a
different image because microtime has changed, but both images are again the
same.
This is supposed to be a random image picker. I don't even care if it's
pseudo-random, as long as I get something that looks like a different image
every time.
any ideas?
