Where does the code take me?

After you select the file you want to upload, you get this screen.

Can anyone tell me where it goes from there?

I understand this part..

<input type="submit" value="Submit" name="upload" class="form_input_submit" onclick="return parent.oPhotoUpload.doValidateFileInfo(this, '533');">

but this part...

<form class="form_advanced" target="upload_file_info_frame_533" action="photos/albums/my/add_objects" method="post" id="photo_file_info_form">                               

The action is what is giving me fits.  From what I understand, it's supposed to go to "photos/albums/my/add_objects" but the way I read it, all this does is create the form.

What I am trying to figure out, is HOW does the code know this is being posted to the wall?

Thanks!

It is handled by an alert.

Now, I have to figure out how to write my own alert!
