2019 and still no pictures of the earth.

The Earth is round - like a ball. A globe, if you will.

How do we know this?

Look at the shadow of the Earth during a Lunar Eclipse that occurs any time other than midnight - that's essentially a shadow of Earth's profile.

It is round. Like a globe.

If the earth is flat, how do you explain traveling constantly in one direction and winding up right back where you started? Also, can you produce 1 person out of the 7 billion people on earth who has actually been to the edge of the earth? If that isn't enough, what keeps the oceans from not simply pouring over the edge like a waterfall? Here's the picture(s) you claim don't exist.

According to flat Earth apologists -

1) "If the earth is flat, how do you explain traveling constantly in one direction and winding up right back where you started?"
~ Their going around in a circle.

2) "Also, can you produce 1 person out of the 7 billion people on earth who has actually been to the edge of the earth?"
~ A few have been, but they're not telling. Not that it'd matter - who'd believe 'em?

3) "...what keeps the oceans from not simply pouring over the edge like a waterfall?"
~ Antarctica isn't a continent. It's like the side of a circular bowl keeping the water on Earth.

4) "Here ARE the picture(s) you claim don't exist..."
~ They're paintings, as asserted in the OP - "The six paintings of the earth are artists renditions."

That's according to flat Earth apologists.
That said, I wholly concur that the Earth is spherical...er, I mean - a bumpy spheroid.
