Presently its not an easy task to compress or resize all images in a document, as a user has to do it manually for each image, so i'm proposing we add checkboxes in the Compress Image dialog to apply the same compression and/or resolution settings to either all images of the same type or all document images.
It's a very good idea
Compressing all images at once is already implemented in presentations (Impress).
How @Yousuf Philips (jay) imagines it in the mockup would be very practical especially for larger documents with many images.
