This is what I first thought, when I read the thread. If what you have in your mind is modifiying the form field via javascript, this does not work.. ;)

That's not what I had in mind, no. :)

ok waiting impatiently here to learn what you have in your mind. I dont need the hack but if you wont give any clue, plz release the hack quick anyway! lol

Ps. BTW temporarily taking the file to the database doesnt count! This is already mentioned in the thread and also too simple hehe

Do you have another idea? Just save the attachment in the database, then in the preview show the "edit attachment" box.

This can cause problems.. What if I choose message preview first, you write the file to database then I simply close my browser?

You have to write a code to periodically check orphaned attachments which causes an unwanted disadvantage and SQL query load, especially compared to small benefit the hack features.. Just my 2 cents..

An extra query on newreply.php will not hurt anyone.
