I have figured out how to draw multiple canvases on top of each other, and will be using .png images to represent links. For example, I have created a 3D-style book in .png format that says "journal" on it and has my logo printed on the book as well. When someone clicks on the book, I want it to open journal.htm. I cannot figure out how to do this, as I am using functions to draw the image in an absolute position so it appears to be on the ground (which is a .jpg background file).
In short, how do I create external links within a canvas when someone clicks on an image within that canvas? For now, I just want to bring up a basic pop-up window that will display data, including links. Later, I plan on adding some animations.
