CodingForums.com - Dynamic drives text rollover script

I have been trying to implement the script here

Code:

http://www.dynamicdrive.com/dynamicindex4/imagetooltip.htm

All image files, js, css and htm files are in the same directory.

However when I roll over the text link, the image box appears with the title but no image. I dont understand as all files are in the same directory.

the line that calls the imgtip is

Code:

<dl><dt><a href="../files/machines/Lapmaster 15 OF 3R.pdf" target="_blank" rel="imgtip[0]">Lapmaster Model 15 Open Face</a></dt>

the js file line is

Code:

tooltips[0]=["AAA2.gif", "Lapmaster model 15", {background:"white", font:"bold 12px Arial"}]

Just cant figure why the image cannot be found...?
