Well found my own solution here for people having the same requirement.
- Insert an Edit HTML module to email template
- Use the code
<center><img src=“{{ contact.upload_your_splash_screen_photo }}” alt=“personalised image” width=“500” height=“500”></center>
NOTE: contact.upload_you_splash_screen_photo is the internal name of the custom file property used in the form to capture the image file upload
Happy to help out if anyone need more explanation
