Section Background Images
When using an image as a section background the following image sizes minimize cropping.
Create images or graphics of the following heights:
S: 2,500 x 300
M: 2500 x 400
L: 2500x600
The safe zone is approximately 350px wide x your section height minus 50px.
You can also choose a custom height and widths to have finer control of your section height and image cropping
Crop Free Images
In image blocks you can you check the “Stretch” image option to force your image to fit. Pro Tip! - use your image as a banner by setting it’s section width to 100% and section height to 10. If your image has a solid color around the edges, set you section background to that color.
Image Accessibility
Make sure your images are labeled correctly. Be sure to set the “Filename” (Block Images) or “Title" (Gallery Images) . This helps users who can’t see the images read you page. Google also indexes your page descriptions. Take a look at this page for guidance on writing great image descriptions.
