The Links panel lists every image (thumbnail, name, page, missing/modified/embedded badge) with Show filters, sorting and thumbnail sizes; its buttons and flyout relink (to a file or a folder), go to, update, edit the original, embed and unembed, show in folder and open Placement Options. Link Info shows format, colour space, location, ppi and effective ppi, dimensions, scale, rotation, size and dates. Edit > Edit Original and the Properties panel's image section reach the same commands. Engine: links.list, links.goTo, links.embed, links.unembed, links.info and links.placementOptions; links.relink and links.update now place the new file as the image's Placement Options say (transforms, bounds, file dimensions, fit, fill, the alignment point, clip to the old bounds). Model: ImageObject.placement. UI: links.editOriginal, links.reveal, ui.placementOptionsDialog; Services.open_file and pick_folder on the desktop.
