a question about jsp-html-struts and images!!!

[madcoders <ma...@hotmail.com>]

hi I am a new member in JSP and I am working on a problem that while selecting an image from the browser(to upload it to a database) I want to show it in the jsp page meanwhile.Can I handle this by struts img tag or I must use javascript??Furthermore when I want to do this in HTML
this is easy but I have to use struts so in HTML there is :

<FORM action=multipart/form-data method=post name=frmInfo> but struts use this:

<html:form action="upload.doqueryParam=Successful"enctype="multipart/form-data">;

in the page ,button, how can understand these different action?
Thank you
