note 26534 rejected from function.getimagesize by didou

Note Submitter: editor@louisvillemusic.com ---- A curious (to me) item cropped up while using GetImageSize() involving full URLs read from a MySQL db. The function only worked when I used strtolower($image) to convert the URL to all lowercase before processing it through the function. In the same section of coding, the <img src=$image> worked perfectly well without converting it to lowercase. Given that the image names were not all lowercase, it certainly seemed quite odd. Anybody have an explanation for this?
