upload file across domains

[omoutop]

I have two (or more) domains on the same dedicated server.
For our example i will use:
www.example1.com
www.example2.com

Is there a way to use a form to upload files from www.example2.com and store them to www.example1.com?

Thanks for any advice.

There may be a much better solution, but could you FTP the uploaded file from example2.com to example1.com? Then delete the file at example2.com?

What happens if you specify www.example1.com/uploadscript.php as the action of the form on example2.com?

I cant use ftp (as is commonly used)
Website users will be able to upload files from one site and these files must be stored on another website.

I have never user php ftp (i am looking at it now)
Also I have thought about:
- frame solution
- popup/modal solution (page will be hosted on storage website)

One question is if this is doable.
One question is about which method is efficient enough.
Another question is if must i change anything in the apache/php.ini configuration?

Yes, I was referring to PHPs FTP functions to establish an FTP connection between servers... ftp_connect(), ftp_login() and ftp_put() [uk3.php.net] which has an example to upload a file from one server to another.
