Presidio: Change Presidio’s Featured Post Image Size

The Presidio theme features a Featured Post at the top of the blog home page. It looks like this:

By default, the Featured Post’s image automatically crops to a horizontal image, with dimensions of 675 x 500px, or 1350 x 1000px on Retina. However, you may wish to change this depending on your photography and typical featured image. Here’s how!

1. Install the Simple Image Sizes plugin.
2. Go to Settings > Media, and you’ll see a list of all of the special sizes registered by the theme and plugins. Change the settings for the featured-post size to your preferred dimensions, and save.
3. Next, you’ll need to regenerate the thumbnail sizes for the featured image in your featured post. Make sure you have installed the Regenerate Thumbnails plugin, if you haven’t already. You were prompted to install this plugin upon activating your theme, so you may already have installed it.
4. Go to the post editor for your featured post. In the Featured Image box to the right, you should see a link to Regenerate image sizes. Click and it will force your featured image to update to the new size.

Of note: If your featured post is set to always show the latest post, WordPress will automatically resize the thumbnail to the new size you’ve selected for any images you upload moving forward. If you choose a specific post to highlight and want to switch it out for another post from your archives, you’ll need to repeat steps 3 and 4 for that post to resize that featured image.
