Hey Chris,
Thanks for replying.
Dont worry about it, I got so p*ssed that I just
striped the whole thing down to pretty much just the
imagecopyresized() function, fiddled around with it to
see how it works and got the sh*t working. The good
thing now is I understand a bit better how the
function works and thanks to you and Trever I learnt
how the first problem works too, not a bad day at all
if I say so myself.
Working on other parts of the scripts now so have not
uploaded the working parts but if you would like to
see it working, just reply.
Cheers,
Mag
