What triggers this issue?
This issue reports pages that have a link to the image files that returned one of the 4xx or 5xx HTTP status codes to our crawler. Such image files are widely known as broken images.
Why is it important?
Since broken images will not be displayed on your pages, they can negatively affect user experience on your website and its authority. Besides, these images won't be indexed in the search results.
How to fix it?
In the "Linked images" column of the report, you can see which images cause this issue.
Most likely, the image file had been moved, renamed, or deleted but the link to it was not modified.
Review the pages that have a link to the broken image and update or remove it. If the image was deleted mistakenly, restore it at the existing URL.
For 5xx HTTP status codes (server errors), you might need to address your web developer or hosting provider. Your server can be misconfigured or overloaded.
