Hi,
First remember how images work in HTML. the <img src=...> attribute is treated as an href, so there are actually two separate HTTP requests: one to render the JSP and one to fetch and display the image.
The only thing that changes if your image is stored in an Oracle BLOB is, instead of <html:image> pointing to a file resource, it has to point to a servlet that you write yourself. The servlet fetches the BLOB from your table, sets the Content-Type properly (image/gif, image/jpeg) and writes the bytes to response.getOutputStream.
One thing to remember is, you _can't_ retrieve images from within an Action because you are only allowed to call response.getOutputStream once during the request and Struts' ActionServlet already appears to do that. So you have to write an actual servlet.
