Is it possible to inject a digital SSL certificate to an image? I know how to sign an executable file (.exe) file or a PowerShell script (.ps1) but is it possible with an image (JPEG)?

You can create a detached CMS signature and pass it along with the JPEG file. The benefit is that the original JPEG file is not modified in any way.
Another idea that comes to my mind is putting JPEG into say PDF and sign the PDF using PDF signing techniques. But this won’t let you easily extract the JPEG (the user will be able to easily view it though).
