Insert rtf files in documentation of a program

Hi Everyone,

I have a documentation for my program, in that through

Document->Upload-> rich text format.

I want to upload a rtf file but it doesn't allow me to do so, it says an error.

I specified the file location in the from field which is in my local system.

But still doesn't allow me to do so.

How can i insert an rtf or jpg or bmp files into the documentation.

Any help will be of great use to me.

Thanks,

Joshua.
