Hallie Pro - First Steps - Resize Large Image Files
After installing the Genesis Framework and Hallie Pro child theme, we highly recommend doing some image cleanup. Chances are you have probably uploaded very large resolution images to your WordPress website. Working with very large images can have multiple negative effects both to your WordPress website and also the speed of your site.
To resize large images, we recommend using the Imsanity plugin. The Imsanity plugin can search your image directory for very large image files, and prompt you to automatically resize them to a more suitable file size.
