how do I post images!?

I’ve successfully posted an image once before, but now cant seem to find the method. Last time, I copied a link from imgur, now all the links are “invalid url”
Is there a guide or known method? What is the specific link style needed?

I figured it out, you have to manually add the “s” in “https”

Go to website and paste the image onto it. Then copy the irl and paste it onto the add image part of dc universe. Hope that helped!!
