I use SC so that I get the fancy border and shading around my images to get an image that stands out in a document. This way an image like
doesn't bleed and appear like
which can bleed into the surrounding background.
My DPI was originally set to 96. I set it to 75 and the images are still showing up tiny in Onenote.
Attachment3 shows a forum post with Onenote's screencap of the image.
I typically just screencap all my images to files and then once I have captured all the images I then drag and drop them into Onenote where they all show up nicely formatted and in the correct order (as long as my file names are sorted correctly)
