As far as I know there is a resize function before the pic is loaded. Nebs set this up 12 years ago, pictures have grown a hell of a lot since then! Maybe a huge pic is overloading the resize function???????
You could try shrinking the pic before uploading and see if that works. A similar thing happens on this site, if the picture is too large, it goes in upside down or sideways.

yep that worked , thanks guys for the heads up
