When new image sizes are added in the theme using Image Size option under Dashboard > Jupiter > Control Panel > Image Size in Jupiter theme, it only applies to the newly uploaded images. In that case, the old images need to be updated with the new dimensions before it’s visible in the page/posts. The thumbnails can be regenerated using the Regenerate Thumbnails plugin.
