SizeFill: Resize All Images & Image Size

SizeFill is an add-on for Google Docs™ that sets the size of the images in a document: the one you click, or every image at once, in every tab.

One image, free: click an image, type its width or height, click Resize. As often as you like.
Every image at once: the same width or height for all, a percentage of the text width, or a scale, in every tab and child tab of the document, images in tables and images placed with wrapped text included. Headers and footers, with their logos, are left as they are.
Fit to the page: 100% of the text width with “Only shrink images bigger than this” shrinks the images that stick out and leaves the smaller ones alone.
Ratio kept: the other side follows, so nothing is squashed or stretched.
Your unit: inches, centimetres, pixels or % of the text width. SizeFill shows how many images it found, and the size of the one you clicked, before anything changes.

Only the size an image is shown at changes, as when you drag its corner: the picture keeps its full quality, and Edit > Undo or File > Version history puts the sizes back.
