Hi guys! My first question here. I'm on an iPad.
I did it! I think.
Click/touch the image you like.
When that image is big, there should be three vertical dots. Click them.
Choose "View Original Image."
The same pic will pop up with the URL you need to copy and paste. Just tap the web address at the top to highlight it. (Sometimes it will ask you to "Select All" to highlight it.)
That's what you pop in to your answer.
