Copy-pasted images are resizing even when set to 100% scale

@wdesign Sounds like the bitmap pixel size (is changing somehow or not showing correctly) when copying from Paint Shop Pro or Photoshop to eM Client (which is unusual) as per images (do paste ok as you say) if you copy them via the Browser or the Windows built-in photo viewer.

My Motorbike Image example above was copied and pasted into eM Client from Paint.net directly into eM Client new message window. I use the menu "edit select all, and then edit copy or ctrl-c.

See original Paint.net Image below showing 1200x1200 pixels at 96dpi 24bit before i pasted it into eM Client.
