Change javascript function

Yes. You can remove the click handler that code sets up, and then add your own with identical code except for the 1 => 0.9 change.

To remove that code's click handler (and all others), use off:

$('.open_copy').off('click');

...and then of course add your own, new click handler.

So in total, then, you'd want this code (after the script tag including theme.js, so this code runs after that code):

$('.open_copy').off('click').click(function(){ // <== Changed
 var that = $(this);
 var copy = that.prev();
 that.parents('.asset').find('.cover').click();
 copy.css('opacity', 0).show();
 if (copy.children('.copy_content').data('jsp')) {
 copy.children('.copy_content').data('jsp').destroy();
 }
 var height = copy.children('.copy_content').css({height: ''}).height();
 if (height < that.parents('.asset').height() - 37) {
 var top = (that.parents('.asset').height() - height)/2;
 top = top < 37 ? 37 : top;
 copy.children('.copy_content').css({'margin-top': top});
 } else {
 copy.children('.copy_content').css({'margin-top': '', height: that.parents('.asset').height() - 37}).jScrollPane();
 }
 if (!that.parents('.asset').find('.close_copy').length) {
 that.prev().append('<a href="#" class="close_copy">Close</a>');
 }
 copy.animate({ 'opacity' : 0.9 }, 500); // <== Changed
 that.fadeOut(500);
 return false;
});

You'll want to check for side effects (for instance, if there's other code that also sets up click handlers on those elements, since the code above will remove them, too).

Javascript support override of variables and methods. You should declare an overriding JS script AFTER import of Theme.js file. So, you can exactly copy/paste that function changing only the values you need to.

Note that, as that function is an event binding, you may need to unbind the onclick event first.
