you test for a NULL value with PHP's isset() function.
if( ! isset($image_name) )
{
... display no image ...
}

Subject: [PHP] Can you use null?
I am wanting to know if I can use null to call up an image? I am writing a
page that talks to calls to a database for cars. There a field where calls
on photo names, but if someone doesn't have a photo. Mysql puts null, I want
to be able to use that null to call an image.
