it is because of the closed bracket
the closed bracket in str_replace(":)"
tells the interpreter that that is the end of the statement
it works with :( because it does not take it as the end of the statement
i'm not sure, but you may have to put a backslash before it i.e. \)

You're right...and I solved it by not bothering with str_replace and just
made a regex using preg_replace. I'm not sure exactly what was going on
with str_replace...but, after playing with it more, it does not seem to be
the ).
Here's the simple regex I used:
$post = preg_replace("/\:\)/", " <img
src=http://www.com.com/forum/emoticons/smiley.gif> ", $post);
$post = preg_replace("/\;\)/", " <img
src=http://www.com.com/forum/emoticons/wink.gif> ", $post);
$post = preg_replace("/\:\(/", " <img
src=http://www.com.com/forum/emoticons/crying.gif> ", $post);

Sorry, but the closing bracket has nothing to do with it because it is
enclosed in "", thus it is part of the string.
As an aside: the code works nicely for me as it is. (Running PHP 4.3.2)

Try using single quotes instead - if you're not interpolating a variable,
it's MUCH better to use ' instead of ", since there's no need for the parser
to check the contents of the string for variable names.
The other point, is that str_replace doesn't change the string directly - it
returns the result of the replace, so you'd need to do
$_POST['Tip'] = str_replace(':)', ' <img src="http://www.com.com/icons/crying.gif" alt="Crying Smiley" /> ', $_POST['Tip']);
or something similar - remember
1 - attribute values should be quoted (src="this.gif")
2 - img tags should be closed (<img src=..... />)
3 - add an alt attribute, so that the img means something even if people don't/can't
display images; and so that this will help you towards writing valid code, depending
on your variant of html/xhtml

the second line works perfectly, however I can't make the first one
