I've got the above on multiple pages of a site - really easy way to display a portfolio of pics of different proportions.
When you click on a pic to view the larger version it works - but when you use the forward and back buttons - (under the enlarged pic OR on the physical keyboard - , the pics do not display in the same order as they are on the web page.
This happens with all the photo grids on this site.

Any ideas?
