In the 'Listing Iimage style' setting, you can choose the shape of the images for the blog post items on your blog or blog category page.
If you select 'Original', then your images will appear with their original ratios on the page. Keep in mind that different images may have different ratios, so your blog post items may display images of different shapes if you select this option.
If you select one of the ratio options, then all the blog post items images will display in that ratio. The first number in each ratio represents the width while the second number represents the height. For example, a 2:1 image would be twice as wide as it is high.
If your image is cropped oddly or doesn't look the way you want it to after adjusting the image style, you may need to change its focal point so that it crops properly when changing the image ratio. Learn how to change the focal point of an image in your gallery in the 'Media' tab in the Govstack main menu.
