Thank you for reply!
I want to know if is possible to use rapidshare's storage space(to upload), without display rapidshare's web page. I want something similar to Google API, wherewith you can use Google's search engine in background, and display search results as you like, on your page.
I need to post upload parameters(ex. file path) in some way to rapidshare upload form, but i don't know how can i do this.

It is possible to upload files to Rapidshare from another page?(not using Rapidshare's own form). How can i do this with PHP?
