Numerous low-quality images should be replaced

[mogsdad]

Many of the screenshots and architectural diagrams in the Admin Guide are of such a low resolution that they are very difficult to read.

Action: Identify all images that need to be updated, then reproduce them with sufficient quality to be readable. Providing that there are no changes to the content of the images, they can replace the originals. Any that have changes will need to have unique names to maintain backwards compatibility for translations.

We'd need to recreate those images; unless we have their raw/vector.
