I have setup Outlook signatures on multiple computers with Outlook 2013 and 2010 using the same graphic images. When they send emails, images from some senders with the same graphics are larger than the others when received. I am having difficulty understanding why the same size image (in pixels) is scaled up for some users and not others. One theory I have is the images were setup for 96 dpi, and when the signatures were created, their Windows Desktop was set for a lower DPI (larger fonts)?
Any help diagnosing this would be appreciated.
