The below code isnt full version but my question is this..
as it should grab an weather image from another site ,how can i built in a security (or IF statement) that when there's something wrong with the connection that it shows a standerd image..
Because if its waiting for the connectiuon and fails it messes up the place..
Any solution..?

if ( ($difference < $q) AND ($filesize!= 0) )
{ }
elseif ( ($difference > $q) OR ($filesize == 0) )

{
$fc = fopen("cache/latest_radar.png", "wb");
$file = fopen ("http://www.test.com/test.png", "rb");
if (!$file) {
$info = "E";
exit;
}
else
{
while (!feof ($file)) {
$line = fread ($file, 4096);
fwrite($fc,$line);
}
}
fclose($fc);
fclose($file);
$info = "F"; }
