Sorry to disagree, but again, pdf images can be vector (like svg) 
and infinitely scaled or raster (bitmap, as a jpg) and in this 
case the quality is on the file. The pdf format only adds and 
envelope around the original jpg image, or in the conversion it 
can be downscaled.

Just to test this you can extract the images from the pdf and 
check their properties. The specific tools depend on your OS of 
choice, but at least in Linux there are many options, some command 
line based and others GUI based.

Sure. But why not simply use a jpg or png?
* Journals accept those formats perfectly well, 
* you will see them with their best quality, and
* you can see them in emacs buffers natively.

Just try it and you'll see that -if I understood you ok- you will 
gain in every dimension. :)

Best...
