While authoring large documents I normally insert images as links only instead of embedding them into the document. For example an operators' manual that I'm working on would be 120MB+ with images embedded and under 7MB after inserting them as links. This saves a lot of time and frustration while saving the document and when the auto save (which is a good thing) runs every 15 minutes. When I use links I create a folder then put all my images along with the ODT file in it so that archival is easy. It is quote possible that one forgets to do this and links to an image in some other folder and finally forgets to include this in the archive. I did little bit of a search to see if there is any way to 'pack' all of the contents along with the document into a single archive (.zip or the like) so that archival is made simple and error free. Please excuse me if a feature is already existing, otherwise please consider adding a feature, perhaps under File > Export menu to create this packed archive.
Have you already asked the community via https://ask.libreoffice.org? I suppose, this way could be the more successful.
Hello Mohith, You can use relative paths -> https://help.libreoffice.org/Common/Relative_and_Absolute_Links Then, you can compress the document and the folder containing the images together. Closing a RESOLVED NOTABUG
