It is recommended that images be sized no smaller than 225px wide by 225 px tall, at 72dpi for optimal fit in all areas of the module. For thumbnails, the best size is 100 px wide by 100 px tall.
Troubleshooting
Use images that match the aspect ratio of the display area. Images with the same pixel dimensions can still be cropped. This can happen if your News Flash container is more horizontal and the source image is square.
Minimum recommended size is 250 by 250px. Choose dimensions that closely match your site’s News Flash layout to reduce cropping.
Keep all images in a widget the same width and height. This helps prevent layout shifting.
If items appear differently on your homepage, it may be because the homepage uses a more horizontal container for News Flashes.
