Is it possible to change the size of the images in the blog gallery template. At the moment there are 3 across the page, I’d like to change this to 4 (which is how it looks in your demo page).
Unfortunately, that option isn’t available at this point in time, but you are welcome to add that as a feature request if you like. The reason the example has 4 across is it makes use of full width whereas your example site is not full width.
