It just depends on how the javascript is written.  If there is variable
manipulation like

img.src = rootdir + 'hover.gif';

then HTTrack will not find the image correctly because all it sees is the
plain text and in this case only "hover.gif".  But if it was written

img.src = '/images/hover.gif';

then the problem is gone because HTTrack can discover the "link".  In this
regard it's just hit and miss with websites, really.

HTTrack is also cross-platform so it can not rely on Windows or IE.
