Steps to reproduce:
1. Create a document with at least one image
2. Select that and press copy
3. Check the contents of the clipboard in the HTML format
The image doesn't exists in the HTML
Put a reference to a local file like MS Word does. This way when using for example IE11, the image can be pasted into a WYSIWYG editor http://ie.microsoft.com/testdrive/browser/Editing_Paste_Image/
Besides IE11, other software might also want to use such references to local files like Outlook: https://bugs.freedesktop.org/show_bug.cgi?id=59236
If I copy the content from LibreOffice to MS Word, the image is lost, only the text is copied (I guess that MS prefers the HTML format because the RTF version in the clipboard includes the image according to the clipboard inspector)
Operating System: Windows 7
please specify which LibO version are you using.
moreover take a look at Bug 78801... are you reporting the same issue or your problem is different?
I've tested right now with LibreOffice 220.127.116.11 (Windows) and it seems that it's working correctly. It embeds the image as a base64 URL and that way it works in all the browsers.
That other bug seems to be about pasting FROM a web page INTO libreOffice, so it was the opposite of this bug :-)
