By default the “Contact Image” field on the Contact screen is active, and unfortunately you can not hide or deactivate it using the Field “Layout Editor“. Most business don’t collect contact images and this field/section just takes up valuable screen space. In order to remove it, you will have connect to the MySQL Database and run the query which will hide the field. Make sure you have a backup before you run any queries on the database.
UPDATE `vtiger_field` SET `presence`=’1′ WHERE `fieldlabel` =’Contact Image’ AND `tabid`=’4′ AND `fieldname`=’imagename’ AND `fieldid`=’108′;
