[PHP] getimagesize with image in database

[Chuck Barnett]

Hi, I'm trying to get an image size from an image in a database.

here's my code
$imagesize = getimagesize(http://domain/image.jpg);
echo $imagesize[3];

but it returns nothing.  If I use a local file, without http  it works.

I have php 4.0.6

any suggestions.

Thanks,
Chuck
