A few questions related to developing a blog....can anyone please help me out??

I am trying to develop a project which is almost like a blog using jsp.I have a few questions....

1. Can anyone tell me if we can insert images inside textarea??Like we do it in blogspot.Right click and paste the image??If it is possible then how is it done??
2. If we can insert images in the textarea then how do I process in the next page?When the user clicks on the submit button and is redirected, in the next page if I mention request.getParameter("textarea_name attribute"),will I get all the contents included in the textarea in the previous page??
3. How do I save the contents of the textarea in the database??
