i can get it working in normal html but fixing it in the php echo statement is my issue.Thanks

Placing all that HTML into a PHP string is just insane. Why on earth are you doing this? Anyway, your funeral...

onerror="this.src='img/delogo.jpg';"

If you have to have those single quotes in the string, then you must escape them as your using a single quoted string in PHP:

onerror="this.src=\'img/delogo.jpg\';"
