This has been mentioned before, but was buried under a different topic.
Currently we can get email notifications when favourite points are posted to a cache. It would be nice to have the same facility with posted photographs, as personally I would like to see them, but I don't get told if any are posted unless it is mentioned in the log.
The email should contain a link to the cache(s), and to the log containing the photo(s), and maybe to the photos themselves.
By the way, this applies to trackables as well as caches. Although I suspect PGC does not collect trackable logs so may not be able to detect trackable photos at the moment.
