This warning occurs if two conceptual content media files with the same filename but from different source locations are copied to the .\Media folder during the build.

Although source image files with the same name can reside in different project folders, all conceptual content images are copied to the .\Media folder during the build. As such, like-named files will overwrite each other. If this is an issue, rename one of the files. The image IDs should remain the same or you will have to locate their occurrences in the topics and update them manually.
