Choose a picture and the node looks at it for a few seconds. Choose
another one in that time and the node finished the first look before it
started on the second, so the new picture sat there while the old one was
still being worked on.
A look gives way to the next job in ComfyUI's queue. The new picture's
run is now sent at once, behind the look that is on its way, which ends
that look within a moment. Its answer is dropped: it is about a picture
the node no longer has.
- Image Crop + Rotate + Pad and Load Image + Pad: the look at the new
picture no longer waits for the old one to be over.
- A plain Load Image: the same, for a look that was on its way when
another file was chosen.
- A second look at the same picture still waits for the first, and
nothing goes behind a run that is no look.
Also: a plain Load Image that had no file when the workflow was opened
was not watched, so the first file chosen on it did not show on the node
until something else made it look again. It is watched now.
