Hi Sheri,
I think you're pretty much there. Since empty() is a function of
string, when $("field_http_"+id).src is undefined, "undefined.empty"
will not be a function. $("field_http_"+id).src will return undefined
any time your img tag lacks a src. Try something like this:
var img = $('field_http_' + id);
if (img.src===undefined || img.src.empty()) {
// there is no value or a blank value for src
} else {
// there is a non-empty string value for src
}
