hi pris,
we can display the either images or logos in two ways in wednynpro, i.e when the logo is on the desktop, when it is in the application server i.e AL11 some directory,
usually we fallow the second procedure in real time, i.e we place the required data which is needed at run time in the application directory, so as per our need we have to display the logo or image on the browser which is available in the application server.
plz go through the link below which have a clear procedure to display the logo.
