You include the link in your post title which is not clickable and simply weird.
And at the end of the day, all you’re doing is pulling images from one website and dumping them here. It adds no value and is why you don’t get upvotes. Create something yourself. Post photos that you take. Do something unique.
Well, I'm not a photographer. I just like looking at nice pics and I was hoping that Steemit would render a clickable thumbnail when posting links, but since that's not the case I downloaded them from 500px, uploaded them on Steemit and added the url.
