onmouseover = showimg; imgthumb.onmouseout = hideimg; imgthumb.onfocus = showimg; imgthumb.onblur = hideimg; the first two lines run the functions when the mouse pointer hovers over and stops hovering over the thumbnail, respectively.

onmouseover, and so forth) is used on html element, all name lookup in the attribute first happens on the element itself, then on the element's form if the element is a form control, then on the document, and then on the window (where the global variables you have defined are).
