Hi. We do get people pretending to be something they are not, including imitating people they have stolen content from. Not that I am accusing you of that. You are still new here and need to find your way. You do need to know that some people who do check for abuse are pretty strict on things like re-use of images, so you need to be aware of that. Ideally you should use your own. For the tea and coffee post it would be fine to you phone snaps as people do not expect professional quality and stock images can seem generic.
Just be yourself, connect with people and have fun. Hive won't make you rich overnight, but there is potential to earn.
Thank you for your guidance and recommendations, @steevc. I really appreciate it. Greets.
