When clicking on a photo in the Newsletter, then it open it with a different photo viewer then I use in Phoca Gallery, which didn't look that great.
Example of a link being opened to a photo from the Newsletter:
/photo-gallery/19-portugal/detail/215-obidos-2-1503243-web
This is what the link looks like to the same photo when opened with the Photoswipe viewer (Pocha Gallery Options -> Detail View -> Detail Window) that I use in the Pocha Gallery:
/photo-gallery/category/19-portugal?start=20#&gid=1&pid=17
