AWS Path for Images and Verify

[Schneids]

I have a couple of related basic questions that I couldn't find direct answers to anywhere. 

First, is it possible to store my photos and videos in an Amazon AWS S3 bucket or CloudFront and enter the path to those in a container field on my local database? If so, what does the path look like (special prefix, etc)?

Next, how can I easily search for records that have missing photos or videos in these container fields? I have tried VerifyContainer and IsEmpty, but I can't get anything to work!  Thanks!
