We use a lot of images that don't specify dimensions. This causes a lot of layout jumps, especially in conjuction with other issues causing a delay in when rendering starts.

Wordpress 5.5 will introduce lazy loading in all images with width/height

Tasks

• Investigate if we need to create additional sizes.
• Identify all images where we don't specify dimensions.
• Specify dimensions in all places where we have them available and that don't require further code changes (or require limited changes).
• Create separate tickets where significantly more work is required.
