I found bug when spoiler images are not displayed:
if forum is installed not in root dirrectory of domain.
i mean, i got vs installed here http://www.somesite.com/forums/ - but spoiler.css uses images only from respective to root dir:

.folded {
	display: block;
	background: transparent url(/images/misc/icon_plus.gif) no-repeat left center;
	padding-left: 14px; 
}

.unfolded {
	display: block;
	background: transparent url(/images/misc/icon_minus.gif) no-repeat left center;
	padding-left: 14px;
}

so i fixed by adding "/forums" to URL in spoiler.css.
