QuickImage is an open-source utility for adding drawings and graphs to your Web applications. It was designed primarily for use with the SteelBlue Application Server, but is general enough to be used in many programming environments. The QuickImage package contains both Java classes that can draw images on the client's browser and a C++ program that can draw images on the Web server. They both interpret the same set of graphics commands, and you only need one version to add drawings to your Web applications.
