This looks useful. I have some UI/UX suggestions.

Clicking on an image to view the detail feels like opening a modal, and I expected to be able to quickly go back to the initial canvas view by pressing the Esc key or clicking on the white background behind the image (rather than having to click on the cross symbol, which is a relatively small click target, especially on a large monitor).

Ideally the editing controls would be visible when viewing a single image, not just on the canvas view.

If the image labels are numbers, then the images are ordered, and it would be nice if the single-image view let you step between them using next/previous arrows, or arrow-key keyboard shortcuts.
