Brian, I actually set the 'Content-Type' to 'image/png' and 'image/x-png' while testing and realized that the '<IMG>' tag took care of the content type weather it was set to test/html or image/png.
Why am I using PHP and Java. Liferay is a Java Portal and it is very good, I do not know of something like it written in PHP. Liferay allows you to create portlets using the QUERCUS tecnology, which converts PHP code to Java byte code. I have created a couple of portlets and they work. My problem at this moment is that the portlet I have develop works to the point that the pie chart file is created as a PNG but I am having problem displaying it as a graph and it displays as binary. The php file works if I run it from my apache server but it displays binary if I run it from within the Liferay portal.
