<p>
Loads a file by invoking the right load handler.
</p>
<p>
This procedure invokes the correct file load handler using magic if
possible, and falling back on the file's extension and/or prefix if
not. The name of the file to load is typically a full pathname, and
the name entered is what the user actually typed before prepending a
directory path. The reason for this is that if the user types
http://www.xcf/~gimp/ he wants to fetch a URL, and the full pathname
will not look like a URL.\"</p>

this is that if the user types http://www.xcf/~gimp/ she wants to

Some file formats allow for embedded thumbnails, other file formats
contain a scalable image or provide the image data in different

procedure that allows GIMP to load a thumbnail preview of the image.
This procedure is then associated with the standard load procedure
using this function.</p>
