Insert image to post directly??

[f0x]

I want to add an option that users can upload and then insert their image into their post just by a few steps.

At first, pop-up a window that user can upload their image (just like the vBB's attachment manager).

When upload finish, all the images that user had uploaded in that window just normally insert into their post (between tag , both in Standard and WYSIWYG editor)

How can I do that? Or if you know their some modification did it, please let me know.

Thanks a lot and sorry about my bad English.
