getimagesize takes too long

[kperoni]

Hey there,

I have a webcam site, where people can post their images to my site (via php/postgresql)

Now when I display these remotly hosted images, they are not always online, when they are offline, I need to display a notonline.gif. Is there anyway to" time out" if it takes too long to check if an image is there?

With the below, It sometimes takes 1 to 2 min. to display 20 records.

Here's what I have done:

//snip

$image_info = @getimagesize("$poswebcamurl");
$type=$image_info[2];

if ($type == 0) { echo" <img width=90 height=75 border=1 src='notonline.gif' alt='click to view site'>";
}

else { echo" <img width=90 height=75 border=1 src='$poswebcamurl' alt='click to view web site'>";}

echo"</a>

//end of snip

Any help would be appreciated.

Thanks, Kevin (www.echowerks.net)

What about testing the stream with fsockopen() or somesuch, and then using getimagesize only if the socket call returns true?
