Quote from Justin L bug 131116 
"Image compression appears to be more accurately a "resize" rather than a
compression. The default compression value is 300dpi (in LO 7.0), and for an
image with a smaller DPI already, it will expand the image to 300dpi,
increasing the filesize for no apparent benefit.  I can't really think of a
reason why anyone would want to force a reverse compression, so probably it
should just do nothing in this case. This will especially be important when
<hopefully> there will be option to compress all images in the document.

When used interactively, it could be argued that the user has all the
information they need to determine whether or not to compress. True enough for
a knowledgable user, but there can probably be some improvements here. One
possibility would be to set the default to min(currentViewsizeDPI, 300) [an
interesting easyhack?]. The other option would be to add a (by default enabled)
checkbox to only compress."
