Hi 99graphics
You can open the file: /templates/ja_eventcamp/acm/contact-info/tmpl/style-1.xml
Look for this line of code:
<field name="contact-info-image" type="media" default="" label="CONTACT_INFO_IMAGE_LABEL" description="CONTACT_INFO_IMAGE_DESC" required="1"></field>
change it to:
<field name="contact-info-image" type="media" default="" label="CONTACT_INFO_IMAGE_LABEL" description="CONTACT_INFO_IMAGE_DESC"></field>
