Slideshow not cycling correctly

[vletroye]

in image_panel.js, when clicking NEXT while being on the last image, PhotoShow is assumed to navigate to the first photo in the linear-pane. And when clicking PREVIOUS while being on the first image, PhotoShow is assumed to navigate to the last photo. But there is a bug IMHO there...

Line 92 should be new_select = $(".linear_panel .item").first();
And line 137 should be new_select = $(".linear_panel .item").last();

Changing these two lines, PhotoShow works as expected. Otherwise, it's stuck respectively on the last/first image...

I did fork the master branch and have create a Pull Request with, among others, that fix: #355
