If you link to a photo it is not stored on the site.
It is not causing extra memory usage. The amount of users on the site at one time will use memory, how many posts are being posted concurrently, that sort of thing.
They're not only conversational pieces, to me they are thought provoking, and in many cases brings me back to a time when things were less complicated, people were different.
For example, I posted a photo of Van Halen. To me, it conjures up thoughts on how a person (Roth) could be charismatic, and makes you wonder of all the powerful people centuries ago, how many were treated differently by the masses simply based on looks? I'm pretty sure Jesus was not a short, pudgy, ugly person. If he were, would the crowds have listened to him?
It may interest you. Brother Bhaktananda was just as you described but Brother Turiyananda told me he was the ‘highest monk on the hill’ and I would work in any capacity to be around him again! The spiritual people I have met in life were for the most part - not that physically impressive - yet their magnetism could affect you in all kinds of elevated ways. On the contrary although I found Roth to be a good stage performer… I would not walk across a street to meet him.
