I can fix it by changing the css top attribute to -225px; however, this only fixes it on one specific page and I need galleries on many pages – each one needing a different top measurement, so this solution doesn’t actually help.
Thanks for your help. That is certainly much improved. It opens at the top now but at least it lets you scroll to see the whole picture; however, it’s still not ideal. See the gallery on this page to see what I mean: http://carrotcreative.ca/believe.html When you click the thumbnail there, it loads so far away from where you click it that it feels obviously “off”. Is there a way to fix that or is that the best it can be?
