[jQuery] click on image doesn't fire event

[CreativeMind]

hi all,
I hav a slideviewer... which works perfectly when i click on any
thumbnail,
main image is shown successfully...but i hav put two images
(#nextImage,#prevImage) and one
 counter label..now when i click on next,prev images , sometime they
work but
not every time.. click event shows as if image isn't clicked..


$(function(){

$('#nextImage').click(function(){
var pictWidth=430;

//some logic

});//endnext

$('#prevImage').click(function(){
alert('previous clicked');
//some logic
});//endprev
});//endready

thx for ur help..
