I don't know any Java, so I need to borrow someone else's code so I can have a pop-up window appear with a full size image when someone clicks on a thumbnail. I'd prefer each new picture to replace the last. Can someone direct me to some free code?
Replace linktothis.html with the file you want to load into the popup window, replace 550 with the desired width of the window, and replace 440 with the desired height of the window.
If the window is left open, clicking another link will load the specified file into the existing window, then bring that window to the foreground.
