I just started a new site so I'm new to all of this but after having trouble with my new blog post not showing all of the images when posted I read to disable the Photon plugin part of Jetpack (http://wordpress.org/support/topic/jetpack-images-not-working)
When I disabled it, the colors on my photos changed quite a bit but all of the photos showed up in my post. So at this point my choice is to post with not all of my images showing or post with all of the images but not in correct colors.
I am viewing on a color calibrated monitor and the pages were clicked on within minutes and viewed side-by-side. I have screen captures of 2 different posts (with same photos) showing this issue that I can provide.
