This feature allows you to make any thumbnail twice (2x) as big as the surrounding thumbnails. Simply double click the image and hit the 2X THUMB SIZE button to turn on. Refresh and see the results.
If you are using our index gallery feature (https://aphotofoliocom.zendesk.com/hc/en-us/articles/115002325793) you can 2x an index thumb as well!
Cool Trick: If you are using Vertical Masonry you can 2X all the horizontal images and your horizontal and vertical thumbs will all be the same size! If using Horizontal Masonry you can 2X all the vertical images for the same effect.
Note: If you are using Vertical Masonry and Maintain Order is set to ON the 2x thumbs are disabled.
Note 2: There will be gaps due to the fact that most images are not uniform in size.
