SportsPress registers image sizes that are used in various templates. These image sizes can be used in custom templates, as shortcode parameters, and even in your own themes and plugins.
The following images will retain the aspect ratio of the original image, using the longer side as the maximum dimension:
sportspress-fit-medium - 300 by 300 pixels
sportspress-fit-icon - 128 by 128 pixels
sportspress-fit-mini - 32 by 32 pixels
