hello, i'm looking for the set, standard images sizes for the Colima theme. i want the images I upload to perfectly fit the existing/placeholder images within the design template. I can happily resize the images I've got outside Squarespace, I just need to find out the exact dimensions. I've been screenshotting the provided images and then cropping the ones i want to replace them with to fit the same size, but this feels like a clumsy way to do it! for example, i want to replace the mountain range images below with portraits of the team members - how do i find out the exact dimensions of the current images so i can keep the layout identical to how it is now? thanks!
