Ok we will reduce the size of image but at http://demo.snstheme.com/sns-nova/index.php/maecenas-molestie.html its not showing 100% correctly some part is missing.
If possible and if you can we increase the size of zoom preview box [that we can see in rights site] may this resolve the issue.

If you can do some needful then please do it, it will be really very appreciated.

Thank you.
