I do think this is a good idea. Research grade observations are more likely to be correct in my experience. Above all, the person who adds the taxon photos should be educated on how to identify a species. However, the California Academy of Sciences, the Smithsonian, and local experts or amateurs who may not have research grade photos but have photos that were in some way independently and correctly confirmed by another expert (such as a professor, curator, or the experienced person). A great, accurately identified photo should not be turned down. My point is mainly that scientific institutions like the California Academy of Sciences should also be considered. Their shots may be more revealing and help for easier identification. Just as I am aware that some many grade photos are misidentified by multiple people, I know that sometimes local experts can be wrong. The person who chooses the taxon photos should be properly informed.
