2x2 images in gallery?Browser Info Environment
You should enter image index as "Big File Index".
Now I ran into another problem, or actually the problem started existing out of nowhere.
I had put multiple 2x2 images in gallery using comma separation and it worked just fine. But now, out of nowhere, the gallery started acting so that it won't let you set but just one 2x2 image in grid. This is weird since it first allowed multiple images to be 2x2 but suddenly lets you have only one 2x2 image.
