Hi,

You can create a After Insert business rule on sys_attachment table that should run only for your custom table.

You can add below script:

(function executeRule(current, previous /*null when async*/ ) {
    var recordId = current.table_sys_id;
    var fileName = current.file_name;
    var attachmentid = current.sys_id;
    var grVar = new GlideRecord('table_name'); // replace your table name here
    grVar.addQuery('sys_id', recordId);
    grVar.query();
    if (grVar.next()) {        
        var attachImage = '<p><img src="/sys_attachment.do?sys_id=' + attachmentid + '"/></p>';
        grVar.u_html_field = attachImage;
        grVar.update();
    }

})(current, previous);

Make sure your BR only runs for your table and attachment is of type image (use correct when to run condition to avoid running it for other type of records)
