Doh! Thanks for the tip...that'll save some lines of code :)

} I would change mabey make sure you catching a digit and the serpator for

Ok. Changed it and you're right - much easier to understand what the
patern is being searched.

} The only solution I can think of is while your looping through the
} images they have build more pattern/replacemen array items
}
} foreach (row in db)
} $pattern[] = /###Image($count+1)###
} $$replacements[] = "<htmlstuff>$image_name</htmlstuff>";
Do you mean:
$patterns[3] = "/###Image($count+1)###/";
$replacements[3] = "<html stuff....";
The problem with this is that I don't know how many rows are going to come
back, since the first/only SQL statement just returns one row [whatever
the current image placeholder is...in this case, ###Image1###. So I need
to loop before I run the SQL statements.
Also, using $patterns[3] again overwrites the first call to it [the one
you recommended i re-write for readablity]. I need to make sure the
$replacements[3] contains all of the html stuff, so it needs a pattern for
the preg_replace call later in the function:
$message = preg_replace($patterns, $replacements, $message);
Thanks for your help with this!
