Whenever I try posting something with an image I've copy-pasted from another site, it immediately shows a broken image tag and stalls indefinitely. (To be clear, it shows the broken image tag when I click Post Now, or occasionally when I edit the alt text. Just copy-paste the image in and do absolutely nothing else? It displays fine. ) I can click out just fine, and the post gets sent to my drafts, with the same broken image tag as when I first tried posting it. And to be thorough, I've tested this with images I personally upload from my hard drive. Those work just fine.
What I'm getting is paste one image, it looks okay, but pasting additional images causes things to break
