Difference between checking "Remember me" and not

I'm curious on what the difference is between checking "Remember me" and not checking it. Without going into a "hack" topic too much, I have a file upload script that "posts" to a php file with global.php included. If I check the remember me box when logging in, everything is grand. If I don't check the box, it looses the login on that page and wants to login again (even though all other windows still show logged in.)

So, basically, what's the difference? It uses cookies either way correct?

If you tick remember me, the cookies are persistent, meaning you can close your browser and open it up again and you will still be logged in. If you don't tick remember me, the cookies will only "live" for the current session.

Weird. What i'm trying to do here is be able to upload multiple files at once. I have it working on my other server (running vb3.0, php4, mysql3) and all is good. I've tried several approaches on the new server (jupload, javapowupload, swfupload), all with no luck (new server php5, mysql5, vb 3.7.3) There is a main script (with global.php included) that posts the files to an upload.php script which processes them (will be used to insert into vb database.) I have it striped down right now to the bare necessities (just upload the files into a chmod 777 dir.) It works fine, but once I include global.php it fails. I figured out the reason is it's bringing it to the login page. If I check remember me, it all works fine. If I just load the page "upload.php" by typing it into the browser (obviously no files POST'd it doesn't ask to login, but if the files are POST'd through the upload script, it looses the login for some reason...
