The popups for the final four images on the page are handled using the technique described in this posting

Although a little more fussy than the first method (window dimensions have to be entered manually) there are certain advantages. The popup window is re-useable; a window title can be added; and the status bar message can be customised.

Add this code to the head section of the page which invokes popups

To obtain the dimensions of an image load it into a temporary page, select it, click on Picture Properties and select the Appearance tab

For each popup required add this code in the body section. Substitute your image name and dimensions.

It is not essential to pre-load images but if you wish to do so follow the instructions in the posting
