the perl is run at the time the javascript is generated (server-
side), not when the javascript is executed (client-side).
you cannot mix perl and javascript and get the behavior you are
expecting. you'll need to use javascript variables there, not perl
variables.
however, you can still initialize your javascript variables from perl:
<script type="text/javascript">
var size = <% scalar @sortedfiles %>;
var imagearray = new Array(size);
// do the for loop in javascript, not perl
// ..etc
</script>

I am seeing a mason variable being incremented when the OnClick event

The currentindex is <%$currentindex%><br> THIS BIT SAYS
CURRENTINDEX==1
<form><input type=button OnClick="nextImage()" value="next"></form>

<%init>
my $currentindex = 0;
