I have an site developed in Java and running on a iPlanet server. There are some images associated with each button in the site. The problem with this site is sometimes the images come out properly and sometimes they don't. I see a red cross mark on the button. Could any one of you plz help me in getting rid of this problem? This error is very inconsistant. And this inconsistancy is pointed out by my client and I have to resolve this ASAP.
