I do it the hard/easy way.

Look through your document for the largest image. While doing that,
guesstimate the average size of your images.

Put all images you are using into a folder.

Download Fast Image (JPG) Resizer for Java at

This will...
mass resize all JPEG/JPG images in a directory

resize images
resize + crop images
resize + fill with background color to get the desired image dimensions
rotate images

Resize images somewhere half way between largest and estimated average
size. Pick your favorite statistical method.

Most images will be of better quality. If you are concerned about
watermarking, it will help there too.

Re-Import into document.

This assumes you have not linked to images.

If images are linked and in same directory, re-size all images into
sub-directory and paste sub-directory extension to URL/address.

Hope this helps.

Good morning and again a strange question.
I am writing a little book that is scheduled to be published as an ebook.
The formatting instructions from the publisher (Smashwords) are
exclusively based on the use of Word.
There is a 10 MB file size limit, which my book exceeds due to the
included pictures.

The instructions urge (I did not know that trick) to "compress all
images in the file".
And this works.

IS there something like that in LO?
I saw mentioning of "Presentation minimizer" on the page
but a search for that extension gives "no results".

Anyway, this is meant for Impress. Is there a trick to do that in Writer?

Thank you.
