You can do something like this:
<?php
for ($i = 0; $i < 20; $i++){
# Generate next TrueColor image:
echo ".";
flush();
}
?>
And the user *should* see a single '.' appear as each image is completed.
NOTES:
You need the flush() because Apache/HTTP buffers output until enough content
is there to make it worth sending. flush() forces the data out the door.
You'd probably really be better off just telling them that the thumbnails
will be finished in about 5 minutes (or however long it takes) and letting
them get on with life. Who wants to sit there watching the dots go by? You
can set up a scheduled task to re-generate the thumbnails requested, and use
a database table to track requests.
