If you upload an image to Shogun, you will see the compressed version by default. Your images are compressed to ensure the best page load speed when loading this image into your page.
Image quality settings
On current Shogun plans, you can choose the image quality level that is served on your site.
If you are familiar with Photoshop's Save for Web feature, compressed images could be compared to saving for Web at 80%. With a plan that offers image quality controls, images can be compared to those saved as a standard JPEG at Maximum quality, if you so choose.
These images focus on quality over file size. They are most beneficial and noticeable to users on high-definition or Retina displays.
Custom Elements
You can also make a Custom Element to host your own images.
Open the Custom Element Editor
Add this code: <img src="{{ image_url }}" alt="{{ alt_text }}" />
You'll notice that when you paste that into the template editor in Shogun, a menu appears on the right letting you configure the variables
Change them so that they get entered on the Sidebar rather than inline
Save your page
Then, you can go into the editor, and your custom element will be visible in the sidebar.
