php & gd

Hi all

I seem to be having crainum gas and need some assistance.

PHP 5.0.5,
gd 2.0.33-2 ( rpm ),

In manipulating images, I allow authenticated users access to upload
images for later viewing. If you upload a 640x480, php creates a
thumbnail automatically ( 128x92 ) and saves in a suitable spot.

Now here is the problem: If before I upload an image I decide since it
was shot landscape and I rotate it 90 degrees then save it, when the
thumbnail is viewed on the web site, you see elongated image material.
If you view the image ( not the thumbnail ) everything is OkieDokie.

Thumbnail : http://www.wishingwellfarm.com/SearchPix.php?GoatID=10
click on the image to see the big version. This is a cropped image...

If you remember correctly, if an image is wider than tall, it is
considered 'landscape'. Ok, so I suppose that you *could* landscape
anything, but in this case:

if ( ( $width/$height) >= 1 ) {
# We are landscape, so image is ... normal
$ThumbWidth = 128;
$ThumbHeight = 92;
} else {
# We are portrait, make it taller than wider.
$ThumbWidth = 92;
$ThumbHeight = 128;
};

I guess that I am asking how to tell the difference between a rotated
original and a original original?

thanks
