My wife has several Writer documents with text and images (.jpg photos) that used to be reasonable in size. After having had them edited on another computer at a workshop - I wasn't there so don't know exactly how - they are still in .odt format but two things happened: All styles were gone and the documents got about 10x larger! I found the reason for the large size to be the photos. To address this problem, a) how do I see properties for images in Writer (did they become bitmaps)? b) is there any "minimizer" function to make the photos smaller?

Documents in OpenDocument file format are stored as compressed zip archives (from LibreOffice Help). Embedded photos are stored in a Pictures directory in the zip archive. You can open the .odt file with an archive manager (you may need to rename the file.odt to file.zip to do this) and view the file sizes.
Resizing: I made a test document with a large embedded JPG image. I extracted the image from the .zip file, resized and reduced the JPG quality, replaced it in the .zip file and renamed it as .odt. The document size went from 1.4 MB to 0.11 MB.
