Image Best Practices
Images add to your content when you follow best practice guidelines. You'll also want to make sure that the images you post are accessible so that all users can access them and they satisfy applicable accessibility legislation.
Accessible images
Images should never replace written text. Instead, they should provide a complementary visual. In order for an image to be accessible, you need to include alt text when you add an image to a content page.
Get permission
Before you upload an image to your website, make sure that your organization has the right to use the image. It can be tempting to find an image online through a web search, but this is often a form of plagiarism and something that your organization should avoid.
Image sizing
Review your style guide to determine the acceptable image size for your website.
