If your image is big and doesn’t fit the popup size you may change option “Image Full Width” from General Options it will fit the image in popup without scrolling.
Gallery has 8 views and 8 sections for design option, so galleries with the same view may be designed the same way, to have another design just choose another view.
Right now the option is not available in plugin options, but you may request customization by contacting firstname.lastname@example.org.
If you have a big gallery with lots of high quality images and want to save loading time, we recommend to use Pagination or Load More option. This options will allow to set how many items to load per page.
The differences are minor but may be important for a certain type of users and websites. Photo Gallery is based on minimalistic backend design and has two new views that are not available in the previous gallery plugins : Masonry and Mosaic views are available in this gallery only, and we have also implemented the newly designed Lightbox.
