When we use below REST endpoint:
~~~
http://localhost:8080/business-central/rest/runtime/group.ID:ArtifactID:1.1-snapshot/process/Process.DefID/image
~~~
Process definition image of version 1.1-snapshot will be downloaded. When I tried to get the LATEST version image but it is not working.Using below url will return "HTTP Status 404"

~~~
http://localhost:8080/business-central/rest/runtime/Group.ID:ArtifactID:LATEST/process/Process.DefID/image

In server.log file below warning messages is logged:
