Check mark means image loaded. Color indicates source. Sorry for bad UX. I was lazy and didn't find a good UTF symbol for X. It's using the https://developer.mozilla.org/en-US/docs/DOM/window.URL.createObjectURL https://developer.mozilla.org/en-US/docs/DOM/window.URL.crea... API to get data on page, so not slow and inefficient like data urls
