Script werkt in FF maar niet in IE (Opgelost)

<script language="JavaScript">

if(document.images)

{ currentslide=1; maxslides=29; slide = new Array(maxslides+1); thumb = new Array(maxslides+1); for(var n=1;n<=maxslides;n++)

{ slide[n]=new Image(76,232); slide[n].src='bellewaerde2006/slide_'+n+'.JPG'; } for(var n=1;n<=maxslides;n++)

{ thumb[n]=new Image(76,58); thumb[n].src='bellewaerde2006/thumb_'+n+'.JPG'; } } function prevSlide()

{ if(document.images) { currentslide--; if(currentslide<1) currentslide=maxslides; document.images['slide'].src=thumb[currentslide].src; } } function nextSlide()

{ if(document.images)

{ currentslide++; if(currentslide>maxslides) currentslide=1; document.images['slide'].src=thumb[currentslide].src; } } function showFullSize()

{document.images['fullsize'].src='bellewaerde2006/slide_'+currentslide+'.JPG'; } </script>
