The ideal images for news and blogs should be landscape-oriented images with a ratio of 1.45:1. It's true that you can add any, uncropped full resolution image to a news or blog, but you may find that some images (like logos or images in square or portrait format) when used as the Image in either News articles or Blog posts are not cropped properly. Specifically, key subject matter may be cropped out.
If you see that important subject matter of the image is getting cut off (example below on the left,) this is typically due to the image size. To fix this, you can add additional white space around the subject matter of the image. We call these "safe margins." Minding safe margins will help you ensure the most important subject matter stays within view.
Below, the image on the left is an example of an un-modified image uploaded as-is. The image on the right is the same image, modified to add space on either side so that the top and bottom is not cropped off.
Note - Remember it is better to use an image that is larger rather than smaller. Campus Suite will do the proportional downsizing as needed. Starting with a very small image to begin usually yields an undesirable result and often has artifacting (image degradation).
A simple rule of thumb: As long as the width of the image divided by the height of the image is around 1.45, the cropping should look good as long as you have minded the safe margins. The image below shows you the safe margins on an image that is sized to 1450x1000. Click here to download this file in PSD format. You can use it to size your images and mind the guides.

The following three examples show three types of images that will look good when attached to news and blogs. The content matter can extend all the way to the edges, but the most important subject matter remains within the safe margins.
