(PHP 4 >= 4.0.4, PHP 5)imagecreatefromstring -- Create a new image from the image stream in the string
imagecreatefromstring() returns an image identifier representing the image obtained from the given string. These types will be automatically detected if your build of PHP supports them: JPEG, PNG, GIF, WBMP, and GD2.
An image resource will be returned on success. FALSE is returned if the image type is unsupported, the data is not in a recognised format, or the image is corrupt and cannot be loaded.
