However, for my page (viewed on Mac Book), the width of the tiled gallery is smaller (attached image) than the image posted normally (without using tiled gallery).
But when my page (viewed on Iphone), the width of the tiled gallery is same as the width of the image posted normally (without using tiled gallery).
Thanks for your help again. I installed the plugin and went to Settings to change the Custom Content Width to the theme’s default content width: 697 pixels.
But the tiled gallery is still not the same width as other normally uploaded images.
