When you switch to our Freyja Theme, or activate a theme for the first time on your website, previously added featured images might show up differently. They might look too big or out of place. This happens because image thumbnails have not been resized/cropped.
If you are loading our theme onto an existing website, we would recommend running the Regenerate Thumbnails plugin, which will go through all your images and resize them according to our theme’s requirements.
You can find and install this plugin by typing “regenerate thumbnails” in the plugin search bar (Plugins > Add New) and following the install instructions. Alternatively, you can download it directly from here: Regenerate-Thumbnails Plugin
