Regarding photos. I noticed :
The guidelines are not only requiring us not to not upload duplicates. Also, similar photos are not allowed.
For a detailed explanation of the photo guidelines please see

Tips for posting media to Maps - Maps User Generated Content Policy Help is also a good read.
And I noticed you already found my suspension tutorial. The post on Typical photo guideline violations is also worth going over.
Best of luck
