Render an Image in GUI

Question

Hello experts!

I've made a GUI that calculates the surface area and volume of several shapes based on User input of discreet information such as length, width, depth, etc.

[IMG]http://i246.photobucket.com/albums/gg88/mustardy85/ScreenShotGUI.png[/IMG]
_______________________________________________________________________________________________________
How do I get java to draw the shapes of images in the BLUE rectangle to the right of the pane. So, if the user clicks on "Cube" it would get a jpeg/png/tiff image from say photobucket or another online server, and draw it on there?

Here is the code;

//GUI_4 - by Danish Khan
//======================================================
//Create a program to calculate area/volume of 2D and 3D 
//version of a shape (e.g. triangle and cone, circle and 
//sphere, etc).  There should be 2 buttons at the top 
//which indicate which version it is. 
//Save as “GUI_4.java”, and drop off.

Are there two parts to your question?
1)draw the shapes of images in the BLUE rectangle to the right of the pane.
2)get a jpeg/png/tiff image from say photobucket or another online server, and draw it on there. There could be a problem here. Unsigned Applets are not allowed to go to any site except the one they were loaded from.

A comment: It's a very small area to draw in.

There is only one part to the question; How can I draw an Image in the blue rectangle to the right of the pane?

Alright, if it can't use another website, how can I get it to render it from my hard drive just for test purposes?

Look at the ImageIO class for methods to read an image file.
In an applet you'll want to use getResourceAsStream to get an inputstream for the image in a jar file and pass that to ImageIO
