I am trying to implement a demo certificate issue for my course project. While converting the aspx page to pdf, the image is not getting displayed at all. The image used here is in my own laptop in the same folder as that of the Certification.aspx file. In another laptop, the image is shown once but again the image is not shown. It is happening in random basis.
Please help.
Thanks.
This is the Certificatication.aspx page
This page shows a course portal logo as an image and a line of text about the certificate.

}
The aspx page gets converts to pdf on the click of the above button.
