Ok excellent. Thanks

One more thing. What's the difference between url_post and redirect_link? Isn't having the redirect_link a bit redundant since post_url is almost like a redirection anyway?

Hi, currently i have a photo gallery where the user inserts album name in the first step, submits form, then proceeds to 2nd step for photo uploads to this album, ultimately these photos are uploaded to directrory gallery/my-album-name. So you see i need to make target_dir dynamic. How can i do this...
