With a plain Load Image wired straight in, the picture shows on the node
as soon as a file is chosen. With Image Crop + Rotate + Pad or Load
Image + Pad it did not: the node showed Show picture and waited for a
press, because those loaders may crop, turn or pad the file, so the file
alone is not the picture.
The node now asks for that run itself. A moment after a file is chosen on
one of those loaders, a setting on it is changed or the wire is made, the
loader's picture is on the node, cropped and all.
- Changes are waited out for 0.7 seconds, so a crop being dragged sends
one run when it rests, not one per step.
- Only in answer to something the person did: opening a workflow sends
nothing, and picks saved with a workflow still wait for their own
press.
- Nothing is sent without SAM 3 wired, or with looks set to "only on a
click or the Look button".
