I'm sorry, but I've only forwarded Hive etiquette to you, so you don't receive downvotes. You obviously haven't read the available documentation explaining this and yes, you must source all images. This is regardless of having the license or that you created them yourself.
Sharing the content of others isn't what most consider enriching the blockchain. Original content does.
Have a great experience.
I would agree that original content enriches the blockchain the most. However, what I do does it too, at a lower level. How many people in the blockchain know that vitamin K2 can decrease coronary calcification? Some person may have learn it from getting in touch with my post. Maybe I can add more lines of my creation, but time is limited for me.
If someone wants to downvote, they are free to do it. It is a free country, a free blockchain. I have found that there are people with power issues that take pleasure on downvoting others. Regardless, they are free to do it
